What is Typically the Result of Receptor Upregulation

Question

What is typically the result of receptor upregulation?
A) A hormone's signal is amplified.
B) The number of receptors decreases.
C) The sensitivity of a cell to a hormone decreases.
D) The number of genes that code for a receptor increases.
E) The concentration of hormone molecules in the blood increases.

Accepted Answer

Receptor upregulation involves an increase in the number of receptors on the surface of target cells, making the cell more sensitive to a hormone or neurotransmitter, thereby amplifying the signal that the hormone sends.
