From two pyruvate molecules, oxidation yields how many CO2 molecules according to the material?

Explanation:
In cellular respiration, carbon becomes carbon dioxide at two points after glycolysis. First, each pyruvate is converted to acetyl-CoA, releasing one CO2 per pyruvate. So two pyruvate molecules release 2 CO2 here. Then each acetyl-CoA enters the citric acid cycle and is fully oxidized to CO2, yielding 2 CO2 per acetyl-CoA. With two acetyl-CoA from the two pyruvates, that adds 4 CO2. Altogether, two pyruvate molecules produce 6 CO2.
