How many CO2 are produced during the transition reaction and the citric acid cycle per glucose molecule?

Answer 1

Two Co2 molecules are produced per citric acid cycle. Since the citric acid cycle occurs twice with every molecule of glucose metabolized, a total of 4 C02 molecules are produces for every glucose molecule

Answer 2

During the transition reaction, one molecule of glucose produces 2 molecules of CO2. Then, during the citric acid cycle, an additional 4 molecules of CO2 are produced per glucose molecule. This results in a total of 6 molecules of CO2 produced during the transition reaction and citric acid cycle for each glucose molecule.
