MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis is a series of reactions that occurs when glucose molecules split into two 3-carbon molecules known as pyruvates, which then release energy in the form of ATP. Starting material for glycolysis is glucose.

Detailed explanation-2: -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-3: -Step 1 of glycolysis uses ATP to phosphorylate glucose by adding a phosphate group to the C6 carbon in glucose. The enzyme responsible for phosphorylation in this step is hexokinase. Step 1 represents an irreversible process in which glucose cannot be reformed without the use of a different enzyme.

Detailed explanation-4: -Glucose is produced by plants through photosynthesis using sunlight, water and carbon dioxide and can be used by all living organisms as an energy and carbon source.

Detailed explanation-5: -Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.
