What are the end products of the Krebs cycle?


Quick Answer

The end products of the Krebs cycle for every two molecules of pyruvic acid include 2 ATP molecules, 10 NADH molecules and two FADH2 molecules as well as six CO2 molecules in the form of waste gas.

The Krebs cycle happens in the mitochondria of a cell, and it’s an important part in generating energy, or ATP molecules. The Krebs cycle occurs right after glycolysis. The substance that begins the Krebs cycle is a 3-carbon molecule called pyruvic acid. The process breaks down the pyruvic acid into acetyl coenzyme A, releasing one of the carbon atoms into carbon dioxide. The cycle then combines Actyl-CoA with oxaloacetic acid to form citric acid, which has six carbon atoms. Enzymes then help synthesize these molecules into two ATP molecules, which is the main energy source for the cell. The Krebs cycle works with the glycolysis procedure to quickly create energy for the cell. Both reactions are critical in the sense that they have to work together. Almost all eukaryotic cells contain mitochondria and undergo this process. Although this occurs only in aerobic reactions where plenty of oxygen is available. Pyruvic acid is a product of the cycle as well even though it’s part of what goes into it.
