Answer to Question #171623 in Biochemistry for Shane L.

Question #171623

Gluconeogenesis

1. Phosphoenolpyruvate is a common substrate found in what two pathways?

2. Why is gluconeogenesis labeled as enzymatic by-pass reactions?

Glycogenolysis

3. Explain the function of glucagon and the reaction that is being catalyzed.

4. Epinephrine, a hormone found in the adrenal gland, stimulates the skeletal muscles to produce glucose-6-phosphate. What is the intended purpose of most of the ATP produced from this reaction?

Glycogenesis

5. This metabolic pathway is activated by what hormone that is found in the pancreas? Explain its function.

(1)Gluconeogenesis

Glycolysis

(2) The reactions of gluconeogenesis has three reactions carried out by several enzymes namely hexokinase, pyruvate kinase, phosphofructokinase, and phosphoglycerate kinase.

(3) Glucagon hormone controls blood sugar levels in the body. It stimulates the conversion of stored glucagon to glues which is released to the body stream.

 The reaction is glycogenolysis

(4) The ATP produced inhibits hexokinase activity.

(5) Insulin hormone

Insulin hormone facilitates the uptake of glucose into muscle cells.
