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, fatty acids and amino acids to carbon dioxide (CO2) through a series of enzyme controlled steps. The purpose of the Krebs Cycle is to collect (eight) high-energy electrons from these fuels by oxidising them, which are carried by NADH and FADH2 to the electron transport chain. The Krebs Cycle is also the source for the precursors of many other molecules and is therefore an amphibolic pathway (meaning it is both anabolic and catabolic).
