Reduced NAD and carbon dioxide
|
Detailed explanation-1: -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.
Detailed explanation-2: -The steps are: Pyruvate is oxidised by enzymes to produce acetate, CH3CO(O)-and carbon dioxide, requiring the reduction of NAD to NADH. Combination with coenzyme A to form acetyl coenzyme A (acetyl CoA)
Detailed explanation-3: -The Link Reaction involves the transfer of electrons from NADH and FADH2 to the electron transport chain, which is made up of a series of electron carriers. This transfer of electrons creates a proton gradient across the inner mitochondrial membrane, producing ATP through the process of oxidative phosphorylation.
Detailed explanation-4: -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.
