WebMar 23, 2024 · This is an energy-conserving stage and does not require the conversion of ATP to ADP. The next phase is also known as the glycolysis pay-off phase. Two events occur during step six. Free phosphate not attached to ATP is used in the phosphorylation of GAP. This is made possible by the enzyme glyceraldehyde 3-phosphate dehydrogenase … WebGAPDH and Glycolysis. GAPDH has a kinase function during glycolysis: it first oxidizes glyceraldehyde 3-phosphate, converting the aldehyde group to a carboxylic acid, and …
Glyceraldehyde 3-phosphate dehydrogenase (abbreviated GAPDH) (EC 1.2.1.12) is an enzyme of about 37kDa that catalyzes the sixth step of glycolysis and thus serves to break down glucose for energy and carbon molecules.
