MUSCLE PHYSIOLOGY

Detailed explanation-1: -During glycolysis, a 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules. true; The initial steps in glycolysis are the additions of two phosphates to the glucose molecule, at the expense of two molecules of ATP.

Detailed explanation-2: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.

Detailed explanation-3: -The molecule is restructured, a second ATP enters, binding another phosphate group to a different carbon atom, and the 6‐carbon energized sugar molecule splits into two 3‐carbon molecules, each with a phosphate group consisting of dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3‐phosphate (PGAL).

Detailed explanation-4: -In glycolysis, a six-carbon sugar known as glucose is split into two molecules of a three-carbon sugar called pyruvate. This multistep process yields two ATP molecules containing free energy, two pyruvate molecules, two high energy, electron-carrying molecules of NADH, and two molecules of water.

Detailed explanation-5: -Glycolysis is the breaking down of one glucose molecule (6 carbons) into two pyruvate molecules (3 carbons). During the process, a net of two ATPs and two NADHs are also produced.
