Question 1

Major action of glucagon on blood glucose?

Answer 1

Increases blood glucose concentration. (1) increases glycogenolysis. (2) increases gluconeogenesis.

Question 2

Major action of glucagon on blood fatty acid and ketoacid concentration?

Answer 2

Increases lipolysis. (inhibition of fatty acid synthesis “shunts’ substrates towards gluconeogenesis.
Ketoacids are produced from acetyl CoA, which results from fatty acid degradation.

Question 3

Major action of glucagon on amino acids?

Answer 3

Amino acids are used for gluconeogenesis (stimulated by glucagon), resulting amino acids incorporated into urea.
