Question

*please explain*

Glucagon does not

a) decrease glycogen synthesis in the liver.

b) decrease glycolysis in the liver.

c)increase TAG breakdown in adipose tissue.

d)decrease glycogen synthesis in muscle.

Answer 1

glucagon is released when blood glucose levels decrease, glucogon increases glycogen breakdown in the liver so that more glucose molecules can be produced which is released into the blood, it also decreases the use of glucose in the liver, that is glycolysis in the liver is decreased in response to glucagon.

glucagon also muscles and inhibits the glycogen synthesis in muscle, so that glucose intake by the muscle cells decreases.

TAG breakdown can produce only acetyl CoA, glucose cannot be produced from TAG so TAG breakdown in adipose tissue is not affected.

c)increase TAG breakdown in adipose tissue.
