Answer:

The correct answer is c) The first statement is true; the second is false.

Explanation:

To be able to perform its role, a hormone must bind a specific receptor in its target cell. The receptor can be located inside the cell (in cytosol) or in the surface of the cell (transmembrane receptor). By regulating the expression of the receptor, the target cell regulates the hormonal activity.

The number of hormone receptors in a cell is not constant, it can vary depending on sereral factors, such as the age of the organisms, the effect of several drugs, mutations or diseases.

Answer:

c) The first statement is true; the second is false.

Explanation:

A hormone can affect the activity of particular cell only if the cell has a specific receptor for the hormone. The receptor can be located outside or inside the cell and will only interact with its specific hormone.

As regards the number of receptors, these can vary according to age or illnesses.
