The Krebs Cycle is also known as The citric acid cycle or TCA cycle (tricarboxylic acid cycle ). Krebs Cycle is cellular respiration, where involves a series of chemical reactions that release the stored energy via oxidation of acetyl-CoA. Explore the Krebs cycle 's steps, key enzymes, and its role in cellular respiration for ATP production in this comprehensive guide. The below mentioned article provides notes on the Krebs’ Cycle . The TCA cycle or Krebs ' cycle (after H. A. Krebs ) is a cyclic sequence of reactions through which pyruvic acid produced in the EMP and EDP is oxidized. The cycle operates in aerobic organisms including animals, plants and microorganisms. The main function of the cycle is to generate energy by oxidation of acetic acid which is produced by decarboxylation of pyruvic acid and fed into the TCA cycle as acetyl-CoA. In that sense ... The Krebs cycle is often considered to be the central hub of cellular metabolism, performing many important biochemical reactions that ultimately produce ATP. This article takes a closer look at the Krebs cycle steps, how it works, what is the purpose of it, its diagram , also where does Krebs cycle occur, its products and more.
