According to the text, what is the net ATP yield from glycolysis and the citric acid cycle combined through substrate-level phosphorylation per glucose molecule?

  • A: 2 ATP
  • B: 4 ATP
  • C: 30-32 ATP
  • D: 53 kcal/mol

Explanation

The text states: 'glycolysis and the citric acid cycle, produce only 4 ATP molecules per glucose molecule, all by substrate-level phosphorylation: 2 net ATP from glycolysis and 2 ATP from the citric acid cycle.' Therefore, the combined net yield is 2 + 2 = 4 ATP.
