Anaerobic glycolysis and mitochoondria

The citric acid cycle (CAC) – also known as the tricarboxylic acid (TCA) cycle or the Krebs cycle – is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP). The citric acid cycle is a key metabolic pathway that connects carbohydrate, fat, and protein metabolism. In eukaryotic cells, the citric acid cycle occurs in the matrix of the mitochondrion.

Mitochondria generate most of the cell’s supply of ATPs, used as a source of chemical energy. A mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. In this video, Prof. Hsieh will explain how the food energy generated by our body and the roles of mitochondria.
