Which of the following are not steroid hormones but still do not act through second messenger system, are small, nonpolar and can be taken orally
Correct answer: D. Thyroid hormones (T3 and T4)
- A. Prostaglandins
- B. Estrogen and progesterone
- C. Insulin and glucagon
- D. Thyroid hormones (T3 and T4)
Explanation
Prostaglandins are regulatory molecules but are not considered hormones. Estrogens and progesterones are nonpolar but are steroids. Insulin and glucagon are polar therefore cannot be taken orally.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
