alleryPer glucose molecule, glycolysis yields a net
A1 ATP and 1 NADH molecule
B0 ATP and 8 NADH molecules
C2 ATP and 2 NADH molecules
D4 ATP and 4 NADH molecules
Answer & Solution
Correct answer: C. 2 ATP and 2 NADH molecules
Glycolysis uses 2 ATP (priming) and produces 4 ATP (substrate-level phosphorylation), so NET 2 ATP.
It also yields 2 NADH (from the PGAL to BPGA step) per glucose.
