Question

Assume Kira went out to eat after the dance competition and consumed an excessive amount of carbohydrates. Which of the following would the pancreas do in order to help her body maintain homeostasis?

A. Secrete glucagon, to stimulate her liver to break down glycogen
and release more glucose into the blood
B. Secrete glucagon, to stimulate her liver to take up the glucose and store it as glycogen
C. Secrete insulin, to stimulate her liver to break down glycogen and
release more glucose into the blood
D. Secrete insulin, to stimulate her liver to take up the glucose and store it as glycogen

Answer 1

D. Secrete insulin, to stimulate her liver to take up the glucose and store it as glycogen

Step-by-step explanation:

Insulin and glucagon are two body hormones that help regulate the level of sugar in the blood, which is an homeostatic process. When food containing carbohydrate is ingested like Kira did after her dance competition, the body digests it into glucose (a sugar). The glucose enters into the bloodstream to be used up as energy source.

At this point, the level of sugar (glucose) in the blood increases, triggering the production of INSULIN hormone by the pancreas. The insulin hormone signals the body cells to absorb the glucose. In order to keep in check the excessive amount of sugar in the blood, some of the cells e.g. liver cells are signalled by insulin to store the excess glucose as glycogen, which will be converted back to glucose later by glucagon hormone when glucose is short in the blood.
