A) List, in order, the three enzymes that catalyze the highly regulated steps in glycolysis. (Don't just enter 1, 2, 3 for reaction numbers - give the reaction number based on the 10 steps of glycolysis.) Reaction # Enzyme Reaction # Enzyme Reaction # Enzyme B) For each of these reactions, name ONE allosteric regulator of the enzyme and whether that regulator inhibits or activates the enzyme.

Can any one do 2 and 3
Pyruvate kinase is one of the irreversible steps of glycolysis. The human genome has four genes that encode different pyruvate kinases, including a muscle specific form and a liver specific form. The liver specific form differs from the muscle specific form since it has additional regulation through phosphorylation by protein kinase A and allosteric regulation by the amino acid alanine. A V. vs. [S] plot of liver pyruvate kinase is shown below. hi...
