Which of the following is NOT an effect of adrenaline?
Correct answer: D. Increased peristalsis and secretion in the gut
- A. Increased heart rate
- B. Conversion of glycogen to glucose in the liver
- C. Dilation of the bronchioles
- D. Increased peristalsis and secretion in the gut
Explanation
Adrenaline prepares the body for fight or flight, so it diverts blood and resources to the heart, muscles and lungs and slows digestion rather than speeding it up. Raising heart rate, releasing glucose for respiration and widening the airways all fit that pattern, which is the quickest way to answer this kind of question. It is secreted by the adrenal medulla and acts within seconds.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
