Correct answer: B. Proteins, steroids and biogenic amines
- A. Biogenic amines only
- B. Proteins, steroids and biogenic amines
- C. Proteins only
- D. Steroids only
Explanation
Hormones are chemical messengers produced by the ductless glands (sometimes by neurons) and transported in the circulation to target cells. They regulate metabolic processes. Chemically, hormones are of different natures like biogenic amines (like thyroxine, adrenaline, etc), proteinaceous or polypeptides (like hypothalamic hormones, etc.), and steroids (like sex hormones and adrenocorticoids).

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.
