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: -Glucose is the reactant; while ATP and NADH are the products of the Glycolysis reaction.

Detailed explanation-4: -In the first step of glycolysis, the glucose ring is phosphorylated. Phosphorylation is the process of adding a phosphate group to a molecule derived from ATP. As a result, at this point in glycolysis, 1 molecule of ATP has been consumed.

Detailed explanation-5: -There are a variety of starting points for glycolysis; although, the most usual ones start with glucose or glycogen to produce glucose-6-phosphate. The starting points for other monosaccharides, galactose and fructose, are also shown.
