Q. Which one of the following pairs of hormones are the examples of those that can easily pass through the cell membrane of the target cell and bind to a receptor inside it (mostly in the nucleus)?

A) Cortisol, testosterone
B) Insulin, glucagon
C) Thyroxine, insulin
D) Somatostatin, oxytocin
Explanation

[Solution from source] Cortisol and testosterone are lipid-soluble steroid hormones that pass through the cell membrane and bind to intracellular (mostly nuclear) receptors. Insulin, glucagon, somatostatin and oxytocin are peptide hormones that bind to membrane receptors; thyroxine enters the cell but insulin does not. Answer (1).
