Photosynthesis is an amazing process that transpires inherently and is one that is required for all living organisms to sustain existence on this planet. The efficiency of this process has sparked inventions, such as the semiconductor-based solar cell, that would allow humans to produce energy in a way that is very similar to that of a plant’s photosynthetic process. In this paper, I will compare and contrast the photosynthetic process with that of semiconductor-based solar cells in their capacities to generate energy while also explaining the application of thermodynamics to each process. In order to discuss the photosynthesis and the semiconductor-based solar cell, it is crucial to understand what is involved in each process and how they could be different or the same. Photosynthesis is the process by which plants and some bacteria use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the fuel used by all living things. The solar cell connects solar energy to convert it into electricity, which is required by all humans. This process can be understood as solar electricity, which is created by using Photovoltaic technology, which is converting solar energy into solar electricity from sunlight. This system is providing sunlight to everyday use constituents such as computers, lighting and electrical equipment. The foremost contrast between photosynthesis and semiconductor-based solar cells is that they require solar energy, or sunlight, to commence the processes. In photosynthesis, plants use chlorophyll, often found in green leaves, to engross solar energy from the sun. Likewise, a semiconductor-based solar cell utilizes photovoltaic (PV) panels, very similar to plant leaves to absorb light. The manner in which light is converted in

These reactions generate heat that, in turn, creates steam that runs the generators to produce electricity. Approximately 1/8th of the electricity produced in the world is derived from nuclear power. In this assignment, you will analyze the use of nuclear power as an energy resource. Respond to the following: •Discuss the scientific and technical concepts related to the use of nuclear power as an energy resource. Address the following in your response: oHow is energy released in a nuclear reaction? oHow are nuclear reactions controlled? oWhat elements are involved in nuclear power production? oWhat nuclear forces are involved? •Explain the advantages and disadvantages of nuclear energy, detailing issues related to production, delivery, cost, radiation, air quality, and waste. •Identify a country whose electricity production infrastructure relies heavily on nuclear power. Compare and contrast the use of nuclear power in the United States with the use of nuclear power in this country.

...Assignment#1 BY: Khalleef Harewood Professor Leah Miller INTRO TO BIOLOGY- SCI 115 Gene mutation is known as a permanent change in DNA. For a three year old this can have a tremendous effect on life for oneself and for a family. The article that I had the opportunity to have read was “Rare gene mutation could claim three-year-old's life” (Jim Bender). The three year olds name is Kaylee. She has been diagnosed with a rear gene mutation enabling her from being able to talk, walk or have the mobility of her own head. She is one of only two children in North America to have this condition. The gene that has gone array is a gene that assists the body in dealing with physical stress and has no known cure. Gene mutation relates very well with this course because it directly reflects our discussions about DNA and the many processes it goes through especially DNA replication and repair. “DNA replication is the process by which a cell copies its DNA” (Study Guide, 2013, p105). Based on the concepts from the course after the process called semiconservative replication, which is the process, that when “one strand of each molecule is parental (old), and the other is new”(Study Guide, 2013, p106). After the strands have been duplicated they form bases and in some instances an incorrect base is added during the replication process. This process is very fast due to DNA polymerases working capability. Just as any fast working part of any kind of machine or person, mistakes...

Comparing Photosynthesis and Semiconductor Based Solar Cells

...Assignment 1 Jon Barberio Professor James Smith SCI 115 April 22, 2012 There are many similarities and also many differences when comparing photosynthesis and semiconductor based solar cells this paper will outline those these as well as give a description of the two cycles. I will also be defining the law of thermodynamics and explaining how it applies to photosynthesis and also semiconductor based solar cells harnessing solar energy. Photosynthesis is the process of converting solar energy into chemical energy in the form of carbohydrates. For photosynthesis to occur a few factors must be present such as water, carbon dioxide, chlorophyll, and light energy. Photosynthesis consists of two sets of reactions the first being the photo portion or light reaction which is the reaction that captures solar energy the second being the synthesis reaction or Calvin cycle reactions which converts that solar energy into carbohydrates (Mader, 2010). For light reactions to occur first light energy enters the cells and is absorbed by the chlorophyll. That Light energy raises the energy level chlorophyll enabling electrons to be freed form the chlorophyll molecules. This makes the chlorophyll molecules positively charged the electrons from hydrogen atoms are attracted to the positively chlorophyll causing water molecules to break apart into oxygen atoms. The elections freed from the chlorophyll and the protons freed from water take part in the chemical reactions in the cell. The reactions...

Photosynthesis vs. Semiconductor Based Solar Cell

...Running head: PHOTOSYNTHESIS VS. SEMICONDUCTOR BASED SOLAR CELL Photosynthesis Vs. Semiconductor Based Solar Cell Biology – SCI 115 23 January 2012 Abstract This paper discusses photosynthesis and how it is used by plants to harness solar energy. It also discusses semiconductor-based solar cells and how they are able to harness solar energy and convert it to electricity. This paper also compares the two types of solar energy systems and provides an overview of how the two systems are alike and how they are different. In closing, this paper will briefly explain how the laws of thermodynamics apply to each of the two energy systems. Photosynthesis Photosynthesis is a process that transfers solar energy, or energy from the sun, into a chemical energy that provides nutrients to plants and animals all over the world. Without these important nutrients, plants, animals and humans would not be able to survive on earth. “Animals and plants get energy by metabolizing nutrient molecules made by photosynthesizers.” (Mader, 2010) Semiconductor-Based Solar Cell Before discussing what a semiconductor-based solar cell is, I would first like to define a semiconductor and then explain how it is used in a solar cell type environment. A semiconductor is, “a class of materials, such as silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber)...
