Answer 1

Answer: (B)

On the basis of their chemical nature, hormones can be divided into groups:
(i) Peptide, polypeptide, protein hormones (e.g., insu lin, glucagon, pituitary hormones, hypothalamic hor mones, etc.), TCT, PTH, Thymosins
(ii) Steroids, e.g., cortisol, testosterone, estradiol and pro gesterone, Aldosterone
• Steroid hormones are derived from cholesterol
• Effect of steroid hormones is slow and long lasting
(iii) Iodothyronines (thyroid hormones: Thyroxine)—De rivative of tyrosine
(iv) Amino-acid derivatives (e.g., epinephrine)—Deriva tive of tyrosine
