Question

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 is (mostly in the nucleus)?

• A. Somatostatin, oxytocin
• B. Cortisol, testosterone
• C. Insulin, glucagon
• D. Thyroxin, insulin

Answer 1

The correct option is B Cortisol, testosterone

Cortisol and testosterone are steroid hormones which are lipid soluble and easily pass through the cell membrane of a target cell and bind to specific intercellular receptor.
All the other hormones mentioned here are hydrophilic hormones, which bind to specific extracellular receptors.
