Detailed explanation-1: -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-2: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.

Detailed explanation-3: -Stage one of cellular respiration is glycolysis. Glycolysis is the splitting, or lysis of glucose. Glycolysis converts the 6-carbon glucose into two 3-carbon pyruvate molecules. This process occurs in the cytoplasm of the cell, and it occurs in the presence or absence of oxygen.

Detailed explanation-4: -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-5: -First Half of Glycolysis (Energy-Requiring Steps) The first half of glycolysis uses two ATP molecules in the phosphorylation of glucose, which is then split into two three-carbon molecules.
