There are three primary pathways for ATP production:
1. Glycolysis: This pathway occurs in the cytoplasm and converts glucose into pyruvate, producing a small amount of ATP and NADH. 2. Krebs Cycle: Also known as the citric acid cycle, this pathway occurs in the mitochondrial matrix and generates ATP, NADH, and FADH2. 3. Oxidative Phosphorylation: This process occurs in the inner mitochondrial membrane and uses the electron transport chain to produce a large amount of ATP.
