The phase of cellular respiration where the majority of adenosine triphosphate (ATP) is generated is Oxidative Phosphorylation. This process includes the electron transport chain and chemiosmosis, which together produce significantly more ATP than glycolysis or the Krebs cycle. The correct answer is B. A. Pyruvate Oxidation: This step produces no ATP directly. B. Oxidative Phosphorylation: This phase generates approximately 28-34 ATP molecules per glucose, making it the primary ATP-producing stage. C. The Krebs Cycle: This cycle produces 2 ATP (or GTP) per glucose molecule via substrate-level phosphorylation. D. Glycolysis: This initial phase produces a net of 2 ATP molecules per glucose via substrate-level phosphorylation. The final answer is B. Oxidative Phosphorylation Send me the next one 📸
