Final Answer:1.Glycolysis: Occurs outside of the mitochondria.2. Electron transport chain: Produces the greatest amount of ATP.3. TCA (Krebs) cycle: Requires acetyl coA as an input.4. Only stage that occurs when Oxygen is not available: Glycolysis.Explanation:1. Glycolysis: This initial stage ofcellular respirationoccurs in the cytoplasm, outside the mitochondria. It involves the breakdown of glucose into pyruvate, generating a small amount of ATP and NADH. Since it doesn't require oxygen, glycolysis is the only stage that can occur under anaerobic conditions.2. Electron Transport Chain (ETC): This final stage takes place in the innermitochondrialmembrane. It is the primary site for ATP synthesis through oxidative phosphorylation, utilizing the energy carried by electrons from NADH and FADH2. The ETC generates the greatest amount of ATP during cellular respiration.3. TCA (Krebs) Cycle: Also known as the citric acid cycle, this stage occurs in the mitochondrial matrix. It requires acetyl coA as an input, which is derived from the breakdown of pyruvate in glycolysis. The TCA cycle generates NADH, FADH2, and GTP (which can be converted to ATP) as energy carriers.4. Only stage that occurs when Oxygen is not available: Glycolysis is the only stage of cellular respiration that can occur in the absence of oxygen. In anaerobic conditions, glycolysis serves as the primary energy-producing pathway, producing ATP through substrate-level phosphorylation.Understanding the sequence and characteristics of each stage of cellular respiration is essential to grasp how cells generate energy from glucose and other organicmolecules.Learn more aboutGlycolysisbrainly.com/question/26990754#SPJ11...
