Student’s question 3: “Describe the three things that determine the strength and impact of a hormone on a target cell?”

This post is a response to a question asked by one of the students of A & P II on endocrine A & P.

The three things that determine how much of an effect a Hormone has on a Target Cell are:

    1. The level of the hormone in the blood.

      In other words, the higher the level of the hormone in the blood, the more likely it is to have a greater impact on the target cell and vice versa.

    2. The Number of receptors on the Target Cell:

      If the target cell has more receptors for the hormone, the effect on the hormone on the target cell would be greater because there is more binding:

3. Affinity (strength of attraction) of the binding:

Put simply, affinity is the measure of attraction the receptor has for the hormone. Think of it as the attraction between a man and a woman. If the attraction is strong, they are likely to be together and the stronger the attraction, the more likely they are to stay together.
