Krebs cycle

• The purpose of this step is for acetyl coenzyme A to enter the next stage, the Krebs cycle.
• In the Krebs cycle, acetyl coenzyme A reacts with a four-carbon molecule to create a six-carbon molecule, and the coenzyme A is then released to be reused in the link reaction.
• The Krebs cycle produces ATP and involves a series of redox reactions linking to these reduced coenzymes, resulting in reduced NAD and reduced FAD.
• The products of one round of the Krebs cycle are three reduced NAD, one reduced FAD, one ATP, and two carbon dioxide molecules.
• If you asked how many of these products would you have for every glucose molecule, the answer is two times each of these molecules because the Krebs cycle happens twice for every glucose molecule.
