During complete aerobic respiration of one glucose molecule, at which stages is carbon dioxide actually released?
A.Pyruvate oxidation and the citric acid cycle, where carboxyl groups are stripped from organic acids
B.Glycolysis and pyruvate oxidation, which jointly dismantle the carbon skeleton
C.The citric acid cycle and oxidative phosphorylation, where reduced carriers unload their cargo
D.Glycolysis alone, since splitting a six-carbon sugar necessarily sheds three carbons
