Pyruvate decarboxylation - Wikipedia

NettetThe glycolytic end-product, pyruvate (plus NAD +) is converted to acetyl-CoA, CO 2 and NADH + H + within the mitochondria in a process called pyruvate decarboxylation. The resulting acetyl-CoA enters the citric acid cycle (or Krebs Cycle), where the acetyl group of the acetyl-CoA is converted into carbon dioxide by two decarboxylation reactions … Nettet14. jan. 2024 · Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH. In eukaryotes, this step takes place in the matrix, the innermost compartment of … NettetWhatever you prefer to call it, the citric cycle is a central driver of cellular respiration.

"NettetIn normal condition, acetyl-CoA is mainly channeled into the Krebs cycle for energy production. In overnutrition state, acetyl-CoA can be used to store excess energy by forming fatty acids. Acetyl-CoA is also the source for cholesterol synthesis. In starved state, acetyl-CoA is converted into ketone bodies. " - How pyruvate is converted to acetyl-coa

NettetFigure 7.11 In the citric acid cycle, the acetyl group from acetyl CoA is attached to a four-carbon oxaloacetate molecule to form a six-carbon citrate molecule. Through a series of steps, citrate is oxidized, releasing two carbon dioxide molecules for each acetyl group fed into the cycle. In the process, three NAD + molecules are reduced to NADH, one … NettetAcetyl-CoA is generated either by oxidative decarboxylation of pyruvate from glycolysis, which occurs in mitochondrial matrix, by oxidation of long-chain fatty acids, or by …
