Krebs cycle
Introduction
The Krebs Cycle can also be called the Citric Acid Cycle (CAC) or the Tricarboxylic Acid (TCA) Cycle. This cycle takes place in the matrix of mitochondria and is the first step of aerobic processing in the cell. The process oxidises glucose derivatives as well as fatty acids and amino acids to carbon dioxide (CO2), most of which enter the cycle as acetyl coenzyme A. The purpose of the Krebs Cycle is to collect (eight) high-energy electrons from these fuels, which are carried by NADH and FADH2 to the electron transport chain. The Krebs Cycle is also the source of the precursors of many other molecules and is therefore amphibolic which means that it is both an anabolic and a catabolic pathway. [1]
