How Do Hormones and Target Cells Recognize One Another

Question

How do hormones and target cells recognize one another?
A) by signs
B) by the location of the target cells
C) by the presence of specific receptor molecules on the target cells
D) by the function of the target cells
E) by the location of the hormones

Accepted Answer

Hormones and target cells recognize each other through the presence of specific receptor molecules on the surface of the target cells. These receptor molecules match with the hormone molecules like a lock and key, and trigger the cellular response to the hormone signal.
