WebThe Krebs cycle is a process that primarily exists to extract ATP from acetyl CoA through a series of oxidation-reduction reactions. Like the Calvin cycle in photosynthesis, the Krebs cycle is regenerative. It provides a range of intermediate compounds used by cells to create a range of important biomolecules. The citric acid cycle (CAC)—also known as the Krebs cycle or the TCA cycle (tricarboxylic acid cycle) —is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. The Krebs cycle is used by organisms that respire (as opposed to organisms that ferment) to generate energy, either by anaerobic respiration or ae… iosh managing safely mock exam questions
