In the oxidation of one molecule of glucose during respiration, 36 molecules of ATP are liberated as follows:
Correct answer: C. 2 ATP molecules during glycolysis 2 in krebs cycle and 32 ATP during respiratory chain
- A. All 36 ATP molecules inside the mitochondria
- B. 2 ATP molecules during glycolysis and 34 ATP during the Krebs cycle
- C. 2 ATP molecules during glycolysis 2 in krebs cycle and 32 ATP during respiratory chain
- D. 2 ATP molecules outside the mitochondria and 34 ATP molecules inside the mitochondria
Explanation
Glycolysis produces 2 ATP in the cytoplasm, and the electron transport chain, along with chemiosmosis, generates approximately 34 ATP in the mitochondria.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
