...Photosynthesis and Respiration and the Links Shawna Smith November 24, 2013 IP2-SCIE206-Biology Photosynthesis and Respiration and the Links The sun plays a vital role in the survival of life on our planet. We all use its light for many reasons. We use it to create energy for some of our basic needs. There are other ways to create energy for some of our daily life, and other living things can create energy by no light source. The energy is produced by photosynthesis and respiration. This helps the cells in every living organism. Photosynthesis is one of the ways that energy is produced. Photosynthesis is only preformed by plants because they contain chlorophyll. “Photosynthesis is the process by which plant cells capture and process the sun’s energy to make this energy available to all living things” (Educational Board [EB], 2012). Photosynthesis happens when the sunlight is captured by the chlorophyll, carbon dioxide enters through the stomata and water enters through the roots. Photosynthesis produces glucose and water. The carbon dioxide is produced by animals which breathe it out and the glucose, which is sugar, is produced by the process of photosynthesis. This production is helpful to both the plants and animals. The oxygen produced as a by-product is used by the animals and humans. The bi-product produced by the animals and humans is used by the plants. They benefit both and help each of them survive. “Photosynthesis occurs in two stages are called the light...

...The Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process. Aerobic respiration is an important process in life as we know it. This process further breaks down molecules and sugars using oxygen. During this process adenosine triphosphate (ATP) is created, used to store and transfer energy to cells throughout the body. (Aerobic respiration, 2010) Photosynthesis and aerobic respiration are both needed for each other to be able to perform their primary functions. One without the other would not work properly. Between both of these processes we receive three main sources; water, carbon dioxide and oxygen. Plants and animals require all three of these in order to live. Carbon dioxide and oxygen are a lot like a circle. Animals need oxygen to live and emit carbon dioxide, while plants need carbon dioxide to produce carbohydrates and omit oxygen, thus completing the circle. (Photosynthesis, 2005) During the photosynthesis stage a plant produces oxygen that aerobic respiration will use in order to break molecules, during this process electrons...

Examine the relationship between photosynthesis and cellular respiration. o Write the general formula for photosynthesis. o Write the general formula for cellular respiration. o Explain the relationship between the two that should be obvious from the formulas. Photosynthesis and cellular respiration are neccesary for all thing living. Photoautotrphs (organisms) need energy to survive. Some of these organisms are capable of absorbing energy from sunlight and using it to produce energy for all living things. This ia a continuos cycle. Photosynthesis captures energy for life on Earth. It is the process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules for growth. In this process Light energy is used to convert Carbon dioxide and water into sugar and oxygen. Thus, solar energy is converted into chemical energy.

...The electron transport chain is found in both mechanisms of cellular respiration and photosynthesis. Cellular respiration uses a series of redox reactions to transfer electrons and protons across a membrane to form an electrochemical gradient whereas photosynthesis harvests the light as its energy source to form its electrochemical gradient. This proton electrochemical gradient is used to power ATP synthesis via ATP synthase. The simplified overall reactions of photosynthesis and cellular respiration exhibit reciprocity to each other in that the starting material of cellular respiration begins with H¬2O and the breakdown of glucose and ends with CO¬¬2 and H2O to create ATP. Photosynthesis initially utilizes energy from light combined with inorganic...

...206 Biology January 20, 2013 IP 2 Abstract Some of the things that will be discussed are how photosynthesis and respiration are linked in order to provide you with energy from the food we eat. The absence of oxygen some cells and organisms can use glycolysis coupled to fermentation to produce energy to your cells. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions. Energy, Metabolism, and Cells Photosynthesis envelopes everything we need to sustain life whether directly related or indirectly related. Biology involves a great responsibility for the safety and well-being of all inhabitants of the earth. Our daily lives and the comprehension of what it takes to keep the various life forms alive are very important, (Nahle, N. 2004). First, you will learn what is photosynthesis and aerobic respiration. Secondly, you will learn the role of fermentation in allowing an organism to generate energy for its cells in the absence of oxygen and how does the energy from the sun end up as chemical energy for the anaerobic organism or cell.

...206 Energy, Metabolism, and Cells – Photosynthesis & Cellular Respiration John Carter August 11, 2013 1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. Photosynthesis can be defined as the process that living organisms such as plants use to translate the sun’s energy into chemical energy. Once the plant has translated the sun’s energy into chemical energy it then releases that energy and makes it readily available to other living things (Vermaas, 2007). Aerobic respiration can be defined as nutrients being converted into useful energy. Respiration allows cells to use the energy stored during the photosynthesis process. It’s the chemical reaction that breaks down the glucose and changes it into a larger amount of Adenosine Triphosphate which is also called ATP (Board, 2012). Plants use sunlight to make ATP for its energy source by creating a series of chemical reactions by producing oxygen as a waste product. Next, animals and human beings eat these plants. The nutrients digested by animals and human beings reverse the process by using the ATP as a source of energy. Our cells use the nutrients from the plants and convert the nutrients in a process that uses oxygen (Board, 2012). Once our bodies have used all the nutrients will be need from those plants our bodies as well as animals release carbon dioxide as waste. Photosynthesis and respiration are both means of converting one state...

...energy necessary to fuel chemical reactions for growth, repair, survival, and reproduction. Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert, light energy from the sun, CO2 from the air & H2O from the earth, into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells in an organism & metabolic process in cells leads to the production of ATP by the breakdown of organic substances. Cellular Respiration is the process in which glucose is broken down in the presence of oxygen to supply a cell with energy. During cellular respiration the energy stored in organic molecules (glucose) may be released during cellular respiration. This energy is temporarily stored in ATP molecules. In many organisms, the process of cellular respiration is concluded in the mitochondria, in which ATP is produced more efficiently. Oxygen is used and carbon dioxide and water are released as wastes. Cellular respiration does not just occur in humans it occurs in all living things and is important to everything because it is vital. It provides us all with energy to perform work, everyday tasks and body functions. Thus in essence, Cell respiration is responsible for sustaining and maintaining life itself. Photosynthesis is the process of converting light energy to chemical energy and storing it in bonds of sugar...

... Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the aerobic harvesting of a chemical energy from organic fuel. The three stages are glycolysis, citric acid cycle, and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? The role of glycolysis is splitting sugar into two parts. This allows the cells to make ATP. When the splitting of the two molecules of ATP happen they turn into two molecules of pyruvic acid and the two electrons carrying NADH are produce. • What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur? The role of the citric acid cycle is to reduce and carry electrons that are high in energy to the next stage. In this stage, glycolysis is converted to acetyl CoA by creating many compounds that can store the high-energy electrons along the ATP molecules. • What is the role of the electron transport system? Include the reactants and the products. Where does it occur? The electron transport system transfers the electrons through electron carriers. The energy that is released by electrons pumps hydrogen ions across the inner membranes of the mitchondrin, thus creating high hydrogen ion concentration.

...Photosynthesis and Respiration Dana L. Houston, BSN, RN BIO/240 October 26, 2015 Tomas Oberding Photosynthesis and Respiration This paper will describe a journey through a plant process of photosynthesis and respiration. This paper will also describe the parts of the plant that is encountered and how it is modified at each stage. Then it will discuss the other molecules and entities that are met along the way at each of the five main stages. Furthermore, it will explain the effects on molecules and the writer. Next, it will conclude the journey by using word formulas for photosynthesis and respiration. Lastly, it will summarize what happens to the writer at the end of the five stage journey. Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of biomass. Only after an animal eats the plant is the potential energy from the sunlight released as kinetic energy for movement and growth. Photosynthesis is the chemical process by which green plants convert sunlight into sugar. In essence, this process transforms a wave of light energy into chemical potential energy, which the plant then stores in the molecular bonds of sugar molecules. The following steps will describe a journey through the photosynthesis process that occurs each time the sun’s light reaches the leaves of...

...10/28/14 Linkage between Photosynthesis and Cellular Respiration The link between photosynthesis and cellular respiration is an inverse relationship. Each cycle depends on one another in order for the "entire cycle" to take place. The completed cycle make certain that life continues to exist on the planet. Both are necessary for living organisms. Photosynthesis is the process by which carbon dioxide is converted into organic compounds from sunlight. Photosynthesis occurs in plants, algae, and some bacteria. The process of photosynthesis is also the source of carbon in organic compounds in human bodies, as well as animals. Photosynthesis provides the oxygen for life and for the process of cellular respiration. The simplest way to explain photosynthesis is (Carbon dioxide + light energy → carbohydrates (sugar) + oxygen). Without photosynthesis, humans would cease to exist. Cellular respiration, in contrast, takes glucose (sugar) and other organic compounds oxidizing them to create carbon dioxide. Cellular respiration can be defined as metabolic reactions in organic cells which converts biochemical energy into adenosine triphosphate, better known as ATP. Cellular respiration also releases carbon dioxide into the atmosphere allowing plants, algae, and bacteria to process the carbon dioxide back into oxygen. The simplest way to explain Cellular Respiration is (Glucose + 6Oxygen --> 6Carbon Dioxide + 6Water). Photosynthesis and cellular respiration is a life cycle that keeps...

...Cellular respiration is a catabolic reaction that takes place cytosol and inside of both outer and inner membranes of mitochondria. Cellular respiration consists of multiple stages that aim to break down glucose into water and carbon dioxide to generate ATP for energy use. Glycolysis in the cytosol, Krebs cycle in the mitochondrial matrix, and oxidative phosphorylation on inner mitochondrial membrane take place in a consecutive order for cellular respiration. The glucose provides as the energy source when electrons mainly come from carbon and received by oxygen molecule in the end of chemiosmosis. The electrons are carried by NADH and FADH2 and finally transferred to the oxygen molecule. ATPs are made both in three stages of cellular respiration. And...

...Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Organic compounds such as glucose store energy in their arrangements of atoms. These molecules are broken down and their energy extracted in cellular respiration. The first stage of cellular respiration occurs in the cytosol, while the second and third stages occur in mitochondria. In cellular respiration, electrons are transferred from glucose to coenzymes such as NAD+ and finally to oxygen; the energy released by this relocation of electrons is used to make ATP (University of Phoenix, 2008). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? During glycolysis, glucose (C6) is broken down to two molecules of pyruvate (C3). Glycolysis occurs in the cytoplasm (cytosol) and does not require oxygen ("Cellular Respiration", n.d.). • What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur? Coenzyme A is removed when the two-carbon compound is attached to a four-carbon compound producing a six-carbon compound (citrate). Each citrate molecule undergoes a series of reactions that removes 2 carbon atoms which are released as CO2. In addition, 3 NADH, 1 ATP, and 1 FADH2 are produced. In addition, the four-carbon compound that began the cycle is regenerated ("Cellular Respiration", n.d.). • What is the role of the...
