Question

how glycerol enter into glycolysis​

Answer 1

Glycolysis (glycolytic pathway)

This process, which may occur in all cells, involves splitting the 6-carbon monosaccharide into two 2-carbon molecules, dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Two ATP molecules are invested initially (hexokinase and phosphofructokinase-1) with the eventual net production of 2 ATP molecules (3-phosphoglycerate kinase and pyruvate kinase). Two NADH are produced by glyceraldehyde-3-phosphate dehydrogenase. The resulting NADH may be reoxidized by lactate dehydrogenase such that NAD+ is regenerated. Fructose can be processed by hexokinase to enter the glycolytic pathway as fructose-6-phosphate.
