Question

Quizplus · Accepted Answer

Leptin stimulates the production of kisspeptin, which is essential for the onset of puberty. Therefore, option B is the most accurate statement. Option A is incorrect as melatonin does not trigger puberty directly, but it plays a role in the regulation of sleep and circadian rhythms. Option C is incorrect as cortisol is not known to inhibit leptin directly, but stress can affect the production of both cortisol and leptin, which can delay the onset of puberty. Option D is also incorrect as high levels of leptin are associated with early puberty, not delayed puberty.
