"Each stage produces ATP, but only the first stage occurs in the cytoplasm."

Explanation: Glycolysis (stage 1) occurs in the cytoplasm and yields a small amount of ATP. The citric acid (Krebs) cycle and oxidative phosphorylation (stages 2 and 3) occur in the mitochondrion and also produce ATP (Krebs via GTP/substrate-level phosphorylation, oxidative phosphorylation produces the bulk of ATP).
