Describe the citric acid cycle

In aerobic condition, pyruvate is broken down to an acetyl group and carbon dioxide is released acetyl combines with coenzyme A forming acetyl coenzyme A the acetyl group from coenzyme A combines with oxaloacetate to form citrate. During a series of enzyme controlled steps, citrate is gradually converted back into oxaloacetate which results in the generation of ATP and release of carbon dioxide. Dehydrogenase enzymes remove hydrogen ions and electrons and pass them to the coenzyme NAD, forming NADH. This occurs in both glycolysis and the citric acid cycle. The hydrogen ions and electrons from NADH are passed to the electron transport chain on the inner mitochondrial membrane
