Why Cellular Energy is Gaining Attention in the US

The citric acid cycle, also known as the Krebs cycle, is the second phase of cellular respiration. This process takes place in the mitochondria and involves the breakdown of pyruvate into acetyl-CoA, which is then fed into the citric acid cycle. The citric acid cycle produces ATP, NADH, and FADH2 as byproducts.

Glycolysis is the first phase of cellular respiration, where glucose is converted into pyruvate through a series of enzyme-catalyzed reactions. This process takes place in the cytoplasm of the cell and yields a small amount of ATP and NADH.
