MUSCLE PHYSIOLOGY

Detailed explanation-1: -It is a series of eight-step processes, where the acetyl group of acetyl-CoA is oxidised to form two molecules of CO2 and in the process, one ATP is produced. Reduced high energy compounds, NADH and FADH2 are also produced.

Detailed explanation-2: -VCAC: Cellular Processes: The Citric Acid Cycle-An Overview: A Closer Look. The Citric Acid Cycle is a series of eight chemical reactions utilized by all aerobic organisms to generate energy. The pathway uses acetyl CoA and oxaloacetate to produce carbon dioxide, ATP, NADH, and FADH2.

Detailed explanation-3: -First, acetyl CoA combines with oxaloacetate, a four-carbon molecule, losing the CoA group and forming the six-carbon molecule citrate. After citrate undergoes a rearrangement step, it undergoes an oxidation reaction, transferring electrons to NAD+ to form NADH and releasing a molecule of carbon dioxide.

Detailed explanation-4: -The Krebs cycle summarizes a circular series of reactions in the mitochondria to metabolize AcCoA to two molecules of CO2 with resultant generation of one molecule of GTP, three molecules of NADH, and one molecule of FADH2.
