Question

Once a hormone enters the bloodstream, it
A)is usually broken down within minutes.
B)remains active for months.
C)is broken down after it has performed its function on target cells.
D)produces enzymes that affect target cells.

Accepted Answer

Once a hormone enters the bloodstream, it will interact with target cells and undergo metabolic breakdown by enzymes in the liver and kidneys. Hormones do not remain active for months, nor do they produce enzymes that affect target cells. While some hormones may be broken down within minutes, others may have a longer half-life and remain active for hours or even days. However, regardless of their duration of activity, all hormones undergo degradation and elimination from the body.
