WebThis cycle ultimately allows the food we eat, such as glucose, to be converted to energy. There are eight steps for the Krebs (TCA or Citric Acid) cycle: 1. Acetyl coenzyme A … WebA turn of the Krebs cycle produces one ATP, three NADH, one FADH 2, and two CO 2 . Acetyl-CoA is not produced during Krebs cycle. It is produced from the decarboxylation of a pyruvate molecule, which occurs before the Krebs cycle can begin.
