- Cellular Respiration
- The process that releases energy from food in the presence of oxygen.
- 6O2 + C6H12O6 --> 6CO2 + 6H2O+ energy
- Oxygen + Glucose --> Carbon Dioxide + Water + Energy
- 6O2 + C6H12O6 --> 6CO2 + 6H2O+ energy
- It has 3 stages: Glycolysis, the Krebs Cycle and the electron transport chain.
- Glucose enters a chemical pathway known as glocolysis. Only 10% is converted to ATP, the rest becomes pyruvic acid.
- Pyruvic acid then enters the Krebs Cycle where a small amout of energy is released.
- The last stage is the electron transport chain. It requires reactants from the first two stages and uses oxygen to extract energy.
- Pyruvic acid then enters the Krebs Cycle where a small amout of energy is released.
- Glycolysis occurs in the cytoplasm and the Krebs cycle and electron transport chain occurs in the mitochondria.
- Glucose enters a chemical pathway known as glocolysis. Only 10% is converted to ATP, the rest becomes pyruvic acid.
- Oxygen and Enegy
- Pathways that require oxygen are said to be aerobic like the Krebs cycle and the electron transport chain
- Pathways that do not need oxygen are said to be anaerobic like glycolysis.
- Photosynthesis removes carbon dioxide from the atmosphere and respiration puts it back. Photosynthesis releases oxygen in to the atmosphere and respiration uses it to release energy from food.
- The process that releases energy from food in the presence of oxygen.
