Question

Quizplus · Accepted Answer

The pineal gland is responsible for producing melatonin, a hormone that helps regulate sleep-wake cycles. The SCN (suprachiasmatic nucleus) is the master clock in the brain that regulates circadian rhythms, including the production of melatonin. When light is detected by the retina, signaling is sent to the SCN, which then inhibits the production of melatonin by the pineal gland. So, the correct answer is (C) melatonin.
