Question

Which of the following is not a steroid hormone?

• A. Cortisol
• B. Testosterone
• C. Progesterone
• D. Glucagon

Answer 1

The Correct Option is D

To determine which of these is not a steroid hormone, it is essential to recognize their classifications:

1. Cortisol: A glucocorticoid steroid hormone produced by the adrenal cortex, involved in the stress response, metabolism regulation, and immune response.
2. Testosterone: An androgen steroid hormone mainly produced in the testes in males and in small quantities in female ovaries, responsible for male sex characteristics.
3. Progesterone: A progestogen steroid hormone involved in the menstrual cycle, pregnancy, and embryogenesis.
4. Glucagon: A peptide hormone produced in the pancreas that raises blood glucose levels by promoting the conversion of stored glycogen to glucose in the liver.

From this analysis, it is clear that Glucagon is not a steroid hormone. It is instead a peptide hormone, differing fundamentally in its structure and biosynthesis method from the other hormone options listed.
