Answer the following questions:
Cellular respiration:
• What is cellular respiration and what are its three stages? Cellular respiration is the process by which cells harvest energy that is stored in food. 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? Glycolysis which mean splitting sugar, with oxygen it is the first step in cell respiration, without oxygen it allows cells to make ATP which is fermentation. In the process of splitting two molecules of ATP, two molecules of pyruvic acid and two electron carrying NADH are produced.
• 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 the high energy electrons to the next stage. The glycolysis is then converted to acetyl CoA through a series of steps creating many compounds capable of storing high energy electrons along with ATP molecules.
• What is the role of the electron transport system? Include the reactants and the products. Where does it occur? The role of the electron transport system is to transfer the electrons through electron carriers. The energy released by electron pumps hydrogen ions across the inner membrane of the mitchondrin, creating high hydrogen ion concentration.
Photosynthesis:
• What is the overall goal of photosynthesis? The overall goal of photosynthesis is to chemically change light into energy.
• Because photosynthesis only occurs in plants, why is it essential to animal life? It is essential to animal life not only for nutrients from the plants but also because of the byproduct oxygen that is put out from the plants from the photosynthesis process.
• What is the role of the light
