Question

An adequate level of the protein ___________ is required to signal the ___________ to increase its production of gonadotropin-releasing hormone (GnRH) and initiate the process of puberty.

Answer 1

The question is incomplete as it does not have the options which are:

• estradiol; pituitary gland
• testosterone; hypothalamus
• leptin; hypothalamus
• leptin; pituitary gland

Answer:

leptin; hypothalamus

Explanation:

Gonadotropin hormones are the peptide hormones released by the nerve cells of the hypothalamus which stimulates the anterior hormone to release the gonadotropins like the LH and FSH hormones.

The GnRH hormone is released when the leptin, a protein hormone secreted by the adipocytes stimulates the GnRH neurons of the hypothalamus to release the hormone in both males and females.

Thus, leptin; hypothalamus is the correct answer.
