The Citric Acid (Krebs) Cycle

The citric acid cycle is a series of reactions that produces two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2.

After glycolysis, pyruvate is converted into acetyl CoA in order to enter the citric acid cycle.

The citric acid cycle is a key component of the metabolic pathway by which all aerobic organisms generate energy.
