Detailed explanation-1: -At the end of the Krebs cycle, the final product is oxaloacetic acid. This is identical to the oxaloacetic acid that begins the cycle. Now the molecule is ready to accept another acetyl-CoA molecule to begin another turn of the cycle.
Detailed explanation-2: -Results of the Krebs Cycle All six of its carbon atoms have combined with oxygen to form carbon dioxide. The energy from its chemical bonds has been stored in a total of 16 energy-carrier molecules.
Detailed explanation-3: -The two acetyl carbon atoms will eventually be released on later turns of the cycle; thus, all six carbon atoms from the original glucose molecule are eventually incorporated into carbon dioxide.
Detailed explanation-4: -A 6-carbon glucose molecule is split into two 3-carbon molecules called pyruvates. Pyruvate is needed in order to create acetyl CoA.
