Answer:
2, CO2
Explanation:
Acetyl CoA (a 2 carbon compound) enters into the TCA cycle and combines with oxaloacetate (4C compound) to form a six-carbon intermediate called citrate. Further reactions include the release of one CO2 during decarboxylation of Isocitrate into alpha-Ketoglutarate and release of the second CO2 during decarboxylation of alpha-Ketoglutarate to form succinyl-CoA. In this way, the 2 carbon atoms that enter the TCA cycle in the form of acetyl CoA are released in the form of 2 molecules of CO2.
