Reaction catalyzed by aldolase
WebThe most important enzyme for regulation of glycolysis is phosphofructokinase, which catalyzes formation of the unstable, two-phosphate sugar molecule, fructose-1,6-bisphosphate ^4 4. Phosphofructokinase speeds up or slows down glycolysis in response to the energy needs of the cell. WebDec 3, 2016 · The reaction is catalyzed by the enzyme glucose 6-phosphate isomerase [ EC 5.3.1.9; also called phosphoglucose isomerase]. A key step in the control of glycolysis follows, a second phosphorylation of fructose 6-phosphate produceing fructose 1,6-bisphosphate (FBP).
