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)?
Correct answer: D. Cortisol,testosterone
- A. Insulin, glucagon
- B. Thyroxine, insulin
- C. Somatostatin,oxytocin
- D. Cortisol,testosterone
Explanation
Steroid hormones such as cortisol, testosterone, estradiol and progesterone, mostly regulate gene expression or chromosome function by the interaction of the hormone-receptor complex with the genome. So, these can easily pass through the cell membrane of the target cell and bind to a receptor inside it.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
