NADH and carbon dioxide

Detailed explanation-1: -Firstly, the link reaction produces one molecule of carbon dioxide and one molecule of reduced NAD. Its final product, acetyl coenzyme A, becomes a primary reactant of the Krebs cycle. The Krebs cycle produces one molecule of FADH2 and three molecules of NADH. It also produces two molecules of carbon dioxide.
Detailed explanation-2: -Pyruvate oxidation. Pyruvate travels into the mitochondrial matrix and is converted to a two-carbon molecule bound to coenzyme A, called acetyl CoA. Carbon dioxide is released and NADH is made.
Detailed explanation-3: -How many acetyl-CoA, carbon dioxide, and NADH molecules are produced in the link reaction for each glucose molecule that undergoes cellular respiration? glucose molecule. Therefore, two acetyl-CoA molecules, two carbon dioxide molecules, and two NADH molecules are produced.
Detailed explanation-4: -The end product of the link reaction, acetyl-coenzyme A, then enters into the Krebs Cycle. The purpose of the Krebs Cycle is to produce energy through the oxidation of acetyl-coenzyme A.
Detailed explanation-5: -The link reaction converts pyruvate produced by glycolysis into acetyl coenzyme A, which enters the Krebs cycle. Acetyl coenzyme A joins oxaloacetic acid to form citric acid. Citric acid undergoes a series of reactions to reform oxaloacetic acid.
