29. Synthesis signal. How does insulin stimulate glycogen synthesis?
Step by step
Solved in 3 steps with 2 images
- Fatty acids appear to stimulate insulin secretion to a much greater extent when glucose is also present. Why is this significant?. Name the three unique reactions in gluconeogenesis.Compare the regulation of glucagon and insulin secretion after a mealhigh in carbohydrates, after a meal low in carbohydrates but high inproteins, and during physical exercise.
- How does insulin contribute in regulation of fatty acid metabolism?Why are the essential fatty acid associated with low incidence of heart disease? Cite some clinical signs of essential fatty acid deficiency. Explain how aspirin can block the synthesis of prostaglandins?How does the amino acid substitution and amino acid chain in protamine zinc insulin help control the rate at which insulin enters blood stream?
- Please explain gluconeogenesis. What is it? Where does it occur and why?Describe the role of insulin in lipid metabolism.One of the modes of regulation of glycogen metabolism involves the hormonal control by covalent modification of the two pathways’ regulatory enzymes.(a). Name these enzymes.(b). Illustrate the cascade of reactions that governs the inter-conversion of theregulatory enzyme that is involved in the glycogen degradation.
