Question: 1 / 400

What hormone is responsible for lowering sugar levels in the blood?

glucagon

epinephrine

insulin

Insulin is the hormone responsible for lowering sugar levels in the blood. This is because insulin promotes the uptake of glucose from the blood into cells, where it can be used for energy.

Option A, glucagon, is actually responsible for increasing sugar levels in the blood by stimulating the breakdown of glycogen in the liver.

Epinephrine, option B, can also increase blood sugar levels by promoting the breakdown of glycogen and inhibiting insulin release from the pancreas.

Option D, cortisol, can elevate blood sugar levels by promoting gluconeogenesis, the conversion of non-carbohydrate substances into glucose.

Therefore, the best answer is C, insulin, as it is the only hormone out of the options that actually works to lower sugar levels in the blood.
