MUSCLE PHYSIOLOGY

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: -Breakdown of Pyruvate Upon entering the mitochondrial matrix, a multi-enzyme complex converts pyruvate into acetyl CoA. In the process, carbon dioxide is released and one molecule of NADH is formed.

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: -It produces: Acetyl coA. Carbon dioxide (CO2) Reduced NAD (NADH)

Detailed explanation-5: -The transition reaction is the transition between glycolysis and the citric acid cycle. The transition reaction converts pyruvate (3 carbons) to acetyl CoA (2 carbons), producing carbon dioxide (CO2) and a NADH as shown below.
