Solution
The correct option is B3CO2 Three CO2 molecules are formed. One CO2 is formed during oxidative decarboxylation of pyruvic acid. Two CO2 molecules are formed in krebs cycle, one during the conversion of 6-carbon oxalosuccinate to 5-carbon α-ketoglutarate and the other during the conversion of α-ketoglutarate to 4-carbon succinyl CoA.
