What are 3 parts of aerobic cell respiration?

Aerobic cell respiration consists of three main stages: glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation. Glycolysis occurs in the cytoplasm, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The citric acid cycle takes place in the mitochondria, generating additional NADH and FADH2 while releasing carbon dioxide. Finally, oxidative phosphorylation occurs along the inner mitochondrial membrane, where the electron transport chain generates a large amount of ATP using the electrons from NADH and FADH2, ultimately consuming oxygen to produce water.
