The Kreb's cycle is a cyclic pathway, which means that the original acceptor molecule, which is acetyl-CoA, is regenerated at the end of the cycle. Therefore, the end product of the Kreb's cycle is the same molecule that started the cycle. The Kreb's cycle does produce ATP molecules and electron carriers such as NADH and FADH2, but these are not the original acceptor or end product of the cycle. Enzymes are not a product of the Kreb's cycle, but rather they are enzymes that catalyze the reactions in the cycle. Different molecules are not the product of the Kreb's cycle since the same molecule is recycled.
