Question

Glucagon causes a. use of fat for energy. b. glycogen to be converted to glucose. c. use of amino acids to form fats. d. Both a and b are correct. e. None of these is correct.

Short answer

d. Both a and b are correct.

Step-by-step solution

a. Use of fat for energy

Glucagon is known to stimulate lipolysis, which is the breakdown of fat (triglycerides) into fatty acids and glycerol, providing energy to the body. Therefore, statement a is correct.

b. Glycogen to be converted to glucose

Glucagon causes the liver to convert stored glycogen into glucose, which is then released into the bloodstream to maintain blood glucose levels. This process is called glycogenolysis. Statement b is also correct.

c. Use of amino acids to form fats

This statement is not related to glucagon's primary functions. Glucagon indirectly influences amino acid metabolism, but it's not responsible for converting amino acids into fats. Statement c is incorrect.

d. Both a and b are correct.

Since statements a and b are both correct regarding the effects of glucagon, statement d is the correct answer.

e. None of these is correct.

As both a and b described accurate effects of glucagon, statement e is incorrect. In conclusion, the correct answer is:

Answer

d. Both a and b are correct.
