Question

Insulin is to glucagon as

a) wet is to dry
b) walking to running
c) morning is to afternoon
d) key is to a lock

Answer 1

wet is to dry

Insulin works 'opposite' to glucagon in that insulin lowers blood sugar (glucose) levels by 'opening' the body's cells to allow glucose to enter them so that it can be used to create energy.

Answer 2

The right answer is A (They are opposed).

Insulin is a hypoglycemic hormone, which lowers the level of glucose in the blood.

To sum up, insulin:

* Brings glucose into cells for energy needs

* Stores the rest as glycogen to make reservations

* Once the full reserve turns everything into fat

Unlike insulin, glucagon is a hyperglycemic hormone (which increases the level of blood sugar) secreted by the pancreas; this time by the alpha cells of the islets of Langerhans. The hormone is produced in response to hypoglycemia caused by insulin (which I recall has lowered the level of glucose in the blood by entering the cells).

It therefore re-increases blood glucose with a reverse mechanism
