A Single Hormone Molecule Can Have Dramatic Effects on a Target

Question

A single hormone molecule can have dramatic effects on a target cell, because it
A)causes the cell to produce thousands of copies of the hormone.
B)initiates a chain of events that amplifies its effect.
C)causes the nuclear membrane to break down and exposes DNA directly to the hormone.
D)becomes surrounded by enzymes that transport it to the nucleus.

Accepted Answer

A single hormone molecule can initiate a chain of events that amplifies its effect through signal transduction pathways. This can include activation of second messengers, activation or inhibition of protein kinases, and changes in gene expression. This amplification allows for even a small amount of hormone to have a large effect on the target cell.
