Which statement best describes testosterone?

• A. A vitamin essential for bone health
• B. A carbohydrate used for energy
• C. A key androgen that promotes both androgenic and anabolic effects
• D. A mineral involved in nerve conduction

Answer: (C)

Testosterone is a steroid hormone that acts as a key androgen, meaning it binds to androgen receptors in many tissues to drive masculine development and characteristics. It’s produced mainly in the testes and, to a lesser extent, in the adrenal glands and ovaries in females. Its androgenic effects include the development of male secondary sexual traits, while its anabolic effects promote protein synthesis and growth of muscle, bone, and other tissues. This dual action—supporting both masculine traits and tissue-building processes—makes it the best description as a hormone with both androgenic and anabolic effects. It’s not a vitamin, a carbohydrate, or a mineral, which is why the other options don’t fit.
