Question

question 23
which hormone is primarily responsible for regulating blood sugar levels?
a adrenaline
b cortisol
c thyroxine
d insulin

Explanation:

Insulin is a hormone produced by the pancreas. Its main function is to regulate blood sugar levels by allowing cells to take in glucose from the bloodstream, thereby lowering blood sugar. Adrenaline (epinephrine) is involved in the "fight - or - flight" response, increasing heart rate and blood flow to muscles. Thyroxine is important for metabolism regulation. Cortisol is related to stress response and metabolism but not the primary regulator of blood sugar like insulin.

Answer:

D. Insulin
