WebGroup of answer choices: Binds substrates in a cooperative manner All statements apply Structurally PFK has multiple subunits Binds substrates in a cooperative manner & Structurally. Phosphofructokinase (PFK) is an enzyme that catalyzes the committed step of glycolysis. Therefore must be highly regulated. WebThis is because the product of this step, fructose 1,6-bisphosphate, can only be used in glycolysis. Therefore, the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate is the committed step for glycolysis. Answer choice A is incorrect, this is the second step in glycolysis and is reversible.

WebThis can happen in two ways: either converting glucose--> pyruvate (glycolysis) or by converting glucose-->glycogen (glucogenesis). Glucagon does the opposite, it promotes any pathway that will increase blood glucose levels.
