Q159 / 180 · AIIMS 2014 · Zoology

Which of the following pairs of hormones can easily pass through the cell membrane and binds to a receptor inside it (mostly in the nucleus)?

  • A
    Insulin, glucagon
  • B
    Thyroxine, insulin
  • C
    Somatostatin, oxytocin
  • Correct answer
    D
    Cortisol, testosterone

Solution

Cortisol and testosterone are steroidal in nature. Steroid hormones are lipid soluble and easily pass through cell membrane of a target cell into the cytoplasm. In the cytoplasm they bind to specific intracellular receptors (proteins) to form a hormone receptor complex that enters the nucleus.

Hence, the correct answer is option: 'D'.
