WebThe third step of glycolysis is the phosphorylation of fructose 6-phosphate, catalyzed by the enzyme phosphofructokinase. A second ATP molecule donates a phosphate to fructose 6-phosphate, producing fructose 1,6- bis phosphate and ADP as products. In this pathway, phosphofructokinase is a rate-limiting enzyme, and its activity is tightly regulated. WebMay 6, 2024 · Fructose is metabolized primarily in your liver. Fructose can be used to make glucose through gluconeogenesis, or it can be used to produce energy through glycolysis. However, in contrast to glucose, fructose enters glycolysis at a step that bypasses the regulatory control exerted by phosphofructokinase.
WebIn the second step of glycolysis, an isomerase converts glucose-6-phosphate into one of its isomers, fructose-6-phosphate. An isomerase is an enzyme that catalyzes the conversion of a molecule into one of its … WebNAD+ is required for glycolysis to continue, and is used in the conversion of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. Carbon atoms from glyceraldehyde, derived through the action of aldolase on fructose 1-phosphate, can enter the glycolytic scheme at the level of glyceraldehyde 3-phosphate, or at the level of 3 …
