Summary Introduction
Introduction:
The Krebs cycle is also known as the citric acid cycle (TCA). It consists of multi-step chemical mechanisms used by all aerobic organisms for releasing stored energy by oxidization of the two pyruvates into high energy yielding molecules such as NADH, FADH2, and some ATP molecules.
