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: -What is glycolysis? Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.

Detailed explanation-3: -In stage 2 fructose-1, 6-bisphosphate is cleaved into 2 3-carbon units of glycerladehyde-3-phosphate. Reaction 1: Phosphorylation of glucose to glucose-6 phosphate. This reaction requires energy and so it is coupled to the hydrolysis of ATP to ADP and Pi.

Detailed explanation-4: -Glycolysis is a partial breakdown of a six-carbon glucose molecule into two, three-carbon molecules of pyruvate, 2NADH +2H+, and 2 net ATP as a result of substrate-level phosphorylation. Glycolysis occurs in the cytoplasm of the cell.

Detailed explanation-5: -Glycolysis begins with the six carbon ring-shaped structure of a single glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate .
