During stress, which hormone elevates blood glucose?

During stress, which hormone elevates blood glucose?

• A. Lowers blood glucose.
• B. Elevates blood glucose.
• C. Increases insulin sensitivity.
• D. Decreases cortisol production.

Answer: (B)

During stress, the body releases hormones that provide quick energy by raising blood glucose. The fast-acting epinephrine (adrenaline) triggers glycogen breakdown in the liver, quickly releasing glucose into the bloodstream. Cortisol, released later, promotes gluconeogenesis and can reduce glucose uptake by some tissues, helping keep blood glucose higher for a sustained period. So choosing the option that describes a hormone causing blood glucose to rise aligns with the stress response, making it the best choice. The other ideas describe actions that would lower glucose or oppose the glucose-raising effect: lowering blood glucose, increasing insulin sensitivity, or decreasing cortisol production.
