Question

Some drugs are called "hormone mimics" because they have structures that are similar to hormones that are naturally produced by the body. Which of the following is a way that a hormone mimic can affect cellular communication?
I.blocking the bodies' naturally produced hormones from transmitting signals
II.causing extra signals to be received by the cells with receptors at the time the drug is given
III.blocking the endocrine system from producing natural hormones

Answer 1

II. causing extra signals.... is the correct answer

This is a common problem in some hyperthyroidism disorders. Proteins that mimic TSH bind to receptors causing the thyroid to produce more T3 and T4.

Answer 2

Answer:

Option II, Causing extra signals to be received by the cells with receptors at the time the drug is given

Explanation:

As the name signifies hormone mimics are the  artificial external hormones that mimic a natural hormone. These hormones being similar in look-alike interacts with the receptors before an original hormone could interact and thus send false signals thereby disrupting the cellular communication.  

Mimic hormones do not inhibit any function of endocrine system, they just take the benefit of their similar looks and thus interact with a receptor before an original hormone could do so.

Therefore, option II is correct
