B
ATP net
C

D

검증된 단계별 안내1
Understand the overall process of glycolysis: one glucose molecule (6 carbons) is converted into two pyruvate molecules (3 carbons each).
Identify the ATP investment phase: glycolysis initially consumes 2 ATP molecules to phosphorylate glucose and its intermediates.
Identify the ATP payoff phase: glycolysis produces 4 ATP molecules through substrate-level phosphorylation when converting intermediates to pyruvate.
Calculate the net ATP yield by subtracting the ATP invested from the ATP produced: Net ATP = ATP produced - ATP consumed.
Conclude that the net ATP yield per glucose molecule in glycolysis under aerobic conditions (ignoring NADH shuttling) is 2 ATP.
