MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.

Detailed explanation-2: -Starting material for glycolysis is glucose.

Detailed explanation-3: -The process begins with Glycolysis. In this first step, a molecule of glucose, which has six carbon atoms, is split into two three-carbon molecules. The three-carbon molecule is called pyruvate. Pyruvate is oxidized and converted into Acetyl CoA.

Detailed explanation-4: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

Detailed explanation-5: -It should be noted that when there is a surplus of glucose, some of the glucose will be converted to glycogen. Later, when blood sugar begins to fall, glycogen can be broken down into monomers of glucose again, which will enter glycolysis.
