The processes of gluconeogenesis and glycolysis are said to be reciprocally regulated. Reciprocal regulation means that a) molecules that activate or inhibit one process have the same effect on the other process. b) one cell predominantly uses glycolysis, whereas another predominantly uses gluconeogenesis. c) molecules that activate or inhibit one process have the opposite effect on the other process. d) opposing sets of molecules, such as ATP and AMP, have opposite effects on the process.

1. Bypassing the pyruvate kinase reaction. Gluconeogenesis and glycolysis are opposing pathways that share seven enzymes. The exergonic steps in glycolysis cannot be simply reversed because that would be too energetically costly. Thus, these steps are "bypassed" in gluconeogenesis with a separate set of enzymes. a. Explain why the reaction catalyzed by pyruvate kinase is energetically favorable and essentially irreversible in the cells. b.Explain how the cells that run gluconeogenesis are able to bypass this step with specific reactions that...

a. Discuss the reciprocal/opposite “hormonal” regulation of the most highly regulated steps of these two pathways. (Remember: there are multiple ways hormones can affect enzyme regulated reactions) (3 pts) [answer here] b. Discuss the reciprocal/opposite “reversible covalent modification” of these two pathways. (3 pts) [answer here] c. Discuss any other reciprocal/opposite type of regulation that occurs in the regulation of these two pathways of glucose metabolism. (3 pts) The two pathway are glycolysis and gluconeogenesis
