Question

Describe Kreb's cycle in DETAIL

Answer 1

The citric acid cycle (CAC) – also known as the tricarboxylic acid (TCA)cycle or the Krebs cycle[1][2] – is a series of chemical reactions used by allaerobic 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 ofadenosine triphosphate (ATP). In addition, the cycle provides precursorsof certain amino acids, as well as thereducing agent NADH, that are used in numerous other biochemical reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest established components of cellular metabolism and may have originated abiogenically.[3][4]. Even though it is branded as a 'cycle', it is not necessary for metabolites to follow only one specific route; at least three segments of the citric acid cycle have been recognized
