This is about carbo and lipid metabolism..?

Question

What are the effects of the following on carbohydrate and lipid metabolism?
1. brain
2. insulin
3. glucagon

Thanks! :)

Answer 1

Glucagon is a hormone produced in the pancreas. Glucagon is used to raise very low blood sugar. Glucagon is also used in diagnostic testing of the stomach and other digestive organs. Glucagon is a 29-amino acid polypeptide acting as an important hormone in carbohydrate metabolism.
Increased secretion of glucagon is caused by:
* Decreased plasma glucose
* Increased catecholamines - norepinephrine and epinephrine
* Increased plasma amino acids (to protect from hypoglycemia if an all protein meal consumed)
* Sympathetic nervous system
* Acetylcholine
* Cholecystokinin
Decreased secretion of glucagon (inhibition) is caused by:
* Somatostatin
* Insulin
Highly technical. Your question cannot be answered properly.
Please see the web pages for more details on Insulin, Glucagon and Lipid metabolism.

Answer 2

Lipid catabolism will take place whilst blood glucose ranges are low, as an occasion, after fasting. on the different hand, lipid anabolism occurs whilst there is too lots blood glucose for the liver and muscle cells to uptake. undergo in techniques that glucagon and insulin are opposing hormones. Glucagon ability 'glucose long previous' from the bloodstream, and consequently insulin is secreted whilst glucose desires to be absorbed from bloodstream. Now you purely ought to look up the biochem names of the anabolic and catabolic pathways of lipid metabolism!

Answer 3

Brain depends totally on glucose for energy . Brain contains a lot of fat but can not use it for energy.
Insulin breaks down sugar specially glucose to release energy for every cell in the body. Insulin facilitates conversion of glucose into glycogen and to convert glucose into lipids as "stored" energy in liver and muscle.
Glucagon exactly has the effects opposite of insulin.
