(a) Interpretation: The effects of increasing the concentration of tissue fructose-1,6-bisphosphate on the rates of gluconeogenesis and glycogen metabolism should be explained. Concept Introduction: Most of the reactions in Glycolysis and Gluconeogenesis reactions are taken place in the cytosol. Therefore, unless there is a metabolic regulation, glycolytic degradation of glucose and gluconeogenic synthesis of glucose will occur simultaneously without a benefit to the cell with huge consumption of ATP. This scenario is controlled by a reciprocal control system which inhibits glycolysis when gluconeogenesis is active and vice versa. Glucose produced by glycogen metabolism is also an energy source for muscle contraction. Regulation of glycogen metabolism is also a reciprocal control of the two-enzyme glycogen phosphorylase and glycogen synthase. Regulation is achieved via both allosteric regulation and covalent modification.

In 3-4 sentences, briefly explain how lactate is formed, the biological effect of lactate, and explain the biochemical process and path for conversion of lactate. 3. The hormones glucagon, epinephrine, and insulin, can regulate blood glucose levels to protect the brain. For each one provide a short explanation as to whether it raises or lowers glucose how it does this, and indicate whether it is metabolic or catabolic.

Glucagon is released from the pancreas in response to low blood glucose levels. It regulates the opposing pathways of glycolysis and gluconeogenesis by altering levels of fructose 2,6-bisphosphate. If glucagon causes a decrease in fructose 2,6-bisphosphate, how does this increase blood glucose levels? Explain..

Therefore, unless there is a metabolic regulation, glycolytic degradation of glucose and gluconeogenic synthesis of glucose will occur simultaneously without a benefit to the cell with huge consumption of ATP. This scenario is controlled by a reciprocal control system which inhibits glycolysis when gluconeogenesis is active and vice versa.

Glucose produced by glycogen metabolism is also an energy source for muscle contraction. Regulation of glycogen metabolism is also a reciprocal control of the two enzyme glycogen phosphorylase and glycogen synthase. Regulation is achieved via both allosteric regulation and covalent modification.

Answer 13

Interpretation Introduction

(d)

To Explain:

The effects of increasing the amount of blood glucagon on the rates of gluconeogenesis and glycogen metabolism should be explained.

Introduction:

Most of the reactions in Glycolysis and Gluconeogenesis reactions are taken place in the cytosol. Therefore, unless there is a metabolic regulation, glycolytic degradation of glucose and gluconeogenic synthesis of glucose will occur simultaneously without a benefit to the cell with huge consumption of ATP. This scenario is controlled by a reciprocal control system which inhibits glycolysis when gluconeogenesis is active and vice versa.

Glucose produced by glycogen metabolism is also an energy source for muscle contraction. Regulation of glycogen metabolism is also a reciprocal control of the two enzyme glycogen phosphorylase and glycogen synthase. Regulation is achieved via both allosteric regulation and covalent modification.
