MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis ultimately splits glucose into two pyruvate molecules. One can think of glycolysis as having two phases that occur in the cytosol of cells. The first phase is the “investment” phase due to its usage of two ATP molecules, and the second is the “payoff” phase.

Detailed explanation-2: -Glycolysis, which translates to “splitting sugars", is the process of releasing energy within sugars. In glycolysis, a six-carbon sugar known as glucose is split into two molecules of a three-carbon sugar called pyruvate.

Detailed explanation-3: -The splitting stage is the second phase in the process of glycolysis. This involves the actual splitting of a molecule of fructose-1, 6-bisphosphate (a 6 carbonmolecule), produced from the Investment Stage of glycolysis, to two 3 carbon molecules.
