(a)
(a) is breakdown of one glucose molecule into two molecules of pyruvate.

True
False
Each glucose molecule, when completely oxidised in liver cells produces 32 ATP.
True
False
Pyruvate is decarboxylated and is oxidised to form acetate that will combine with coenzyme A to form acetyl coenzyme A.
True
False
Pyruvate oxidation is the stage in cellular respiration that links glycolysis to oxidative phosphorylation.
True
