Question

Which of the following statements is true? a. carbohydrate rich meal increases insulin secretion b. a protein rich meal increases glucagon secretion c. a carbohydrate rich meal decreases glucagon secretion d. exercise will increase glucagon secretion e. all of the statements are true

Answer 1

Answer:

E- All of the statements are true

Explanation:

Insulin and Glucagon are hormones, both secreted by the pancreas.

Insulin functions in the conversion of carbohydrates to glycogen which is stored in the body as glucose reserves. This implies therefore that:

• A carbohydrate rich meal will stimulate the increased production of insulin.

Glucagon on the other hand, works to breakdown the glucose reserves in situations such as fasting or increased physical activity to make energy available for the body. Glucagon also functions in gluconeogenesis which is the conversion of other nutrient molecules other than carbohydrate, such as amino acids and lactate into glucose to provide energy for the body.

The function of glucagon therefore implies that:

• A protein rich meal will increase glucagon secretion
• A carbohydrate rich meal will decrease glucagon secretion since it functions on other food molecules
• Exercise will increase glucagon secretion
