Question

What would interfere with the binding of estrogen to the estrogen receptor?

Multiple Choice

A.) A molecule that interferes with second messenger cascades

B.) The estrogen receptor cleaves estrogen, making it inactive

C.) A molecule that prevents estrogen from entering the nucleus

D.) A different molecule that binds to the estrogen receptor on the surface of the cell

Answer 1

A different molecule that binds to the estrogen receptor on the surface of the cell
Explanation:
There are an array of foreign compounds (green) which mimic like natural hormones and bind to the receptor, they are although different in shape and structure, can travel in the bloodstream, contact or enter a cell, and bind with a nuclear receptor. Chemicals that produce an abnormal response include compounds like the insecticides kepone and o,p’-DDT and its metabolite o,p’-DDD or the detergent alkylphenol polyethoxylate ,Kepone, o,p’-DDT, and alkylphenols can cause an estrogen-like response.. These kinds of estrogen artificial or chemical structure can enhance female traits in males or cause permanent birth defects that endanger survival and reproduction . In addition, kepone and o,p’-DDD can block progesterone receptors on the outside membrane layer of sperm cells, preventing them from becoming competent to fertilize eggs.
Tamoxifen which is also a mimic or similar structure help to prevent certain type breast cancers.
