Which pair of hormones act antagonistically?
Correct answer: C. Glucagon and insulin
- A. Glucagon and Cortisol
- B. Insulin and Adrenalin
- C. Glucagon and insulin
- D. Glucagon and Adrenalin
Explanation
Glucagon and insulin are hormones that work in tandem to regulate blood sugar levels, rather than acting as direct antagonists. Insulin promotes the uptake of glucose from the bloodstream into cells, reducing blood sugar levels, while glucagon acts to increase blood sugar levels by stimulating the liver to release stored glucose into the bloodstream. Both hormones play essential roles in maintaining glucose homeostasis, working together to ensure the body's energy needs are met under varying conditions. Their coordinated actions help prevent extreme fluctuations in blood glucose levels, contributing to overall metabolic balance.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
