Cellular Respiration
Key Concepts:
1. Cellular respiration is the controlled release of energy in the form of ATP from organic compounds in cells.
2. In cell respiration, glucose in the cytoplasm is broken down into pyruvate, with a small yield of ATP.
3. Cellular respiration can occur without oxygen present (anaerobic respiration) or with oxygen present (aerobic respiration)
4. During anaerobic cell respiration, pyruvate can be converted in the cytoplasm into lactate, or ethanol and carbon dioxide, with no further yield of ATP.
5. During aerobic cell respiration, pyruvate can be broken down in the mitochondrion into carbon dioxide and water with a large yield of ATP.
