Learn about the Krebs cycle diagrams with some examples of the cycle that we have provided below. This cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins, into adenosine triphosphate (ATP) and carbon dioxide.
With so many components in a cycle, it might be a tad confusing to understand them all at once. Check out the following images below!
The Krebs cycle was first elucidated by scientist “Sir Hans Adolf Krebs” (1900 to 1981). He shared the Nobel Prize for physiology and Medicine in 1953 with Fritz Albert Lipmann, the father of the ATP cycle. The purpose of the Krebs Cycle is to collect (eight) high-energy electrons from these fuels by oxidizing them, which are transported by activated carriers 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). Examine the following Krebs cycle diagram below.
The citric acid cycle is a key metabolic pathway that connects carbohydrate, fat, and protein metabolism. The reactions of the cycle are carried out by eight enzymes that completely oxidize acetate, in the form of acetyl-CoA, into two molecules each of carbon dioxide and water. The citrate is rearranged to form an isomeric form, isocitrate by an enzyme acontinase.
