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. Lastly, you will learn how enzyme catalyzes a reaction and the three main steps of the cycle of enzyme-substrate interactions plus how enzyme activity is regulated by the cell.
1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat.
A. Photosynthesis is the process by which plants use energy created from the sunlight; producing and storing sugar (carbohydrate). The conversion of light energy to chemical energy is associated with the photosynthesis process of chlorophyll and the green pigmentation of plants, according to (www.biology.clc.uc.edu. 2000). Plant leaves are the most significant focal point of photosynthesis. There are four parts to the plant leaves. The first one is the upper and lower epidermis. The
