D.prolactin and thyroid hormone

Answer 1

Hormones made from cholesterol include estradiol and testosterone, which are steroid hormones produced by the gonads and endocrine glands.

Step-by-step explanation:

The hormones that are made from cholesterol are estradiol and testosterone. These are examples of steroid hormones, which are derived from lipids, primarily cholesterol. Steroid hormones are produced by the gonads and endocrine glands, and include not just estradiol and testosterone, but also hormones like cortisol and aldosterone, which are secreted by the adrenal glands. These hormones are fat-soluble and can diffuse across plasma membranes of target cells to bind with receptor proteins and influence gene expression.

Answering the question, regarding hormones made from cholesterol, the correct option is A: estradiol and testosterone.

Answer 2

Cholesterol is the precursor of the five major classes of steroid hormones: progestagens, glucocorticoids, mineralocorticoids, androgens, and estrogens. These hormones are powerful signal molecules that regulate a host of organismal functions. Therefore, the answer is A. Estradiol and testosterone.
