Photosynthesis and Cell Respiration
Courtney Chen and Lindsey Reimer
What is Photosynthesis?
There are 3 stages of photosynthesis. In Stage 1 energy is captured from the sunlight. In Stage 2, light energy is converted to chemical energy which is stored in ATP. In Step 3, chemical energy in ATP powers the formation of organic compounds using carbon dioxide. This energy is stored in chemical bonds of glucose. The products of photosynthesis are sugar and water.
Chemical Equation of Photosynthesis: 6CO2 + 6H2O =light energy=> C6H12O6 + 6O2
What is Cellular Respiration?
There are 3 stages of Aerobic Cellular Respiration. Glycolysis which breaks down the glucose, Krebs's cycle which releases carbon dioxide, and the electron transport chain where water is released and the production of ATP occurs. There is a total of 36-38 ATP that are created during aerobic cellular respiration, which provides most of the energy for the cell.
Anaerobic cellular respiration continues to make ATP through glycolysis. This takes place in the cytoplasm. It has 2 different types of fermentation, Lactic Acid and Alcoholic. They both only generate 2 ATP, which is a very little amount.
Chemical Equation of Cellular Respiration: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
