The total of number of CO2 and NADH+H+ produced in Krebs cycle during aerobic breakdown of a molecule of glucose is

Through kreb cycle3 molecules of NADH+H+ and 2 molecules of CO2 are produced. For 1 molecule of glucose the kreb cycle is repeated twice. Therefore, the total number of CO2 produced is 4 and NADH+H+ produced is 6.
