If receptor molecule is removed from target organ for hormone action, the target organ will :

Options

A. Continue to respond but require higher concentration of hormone
B. Continue to respond but in opposite way.
C. Continue to respond without any difference
D. Not respond to hormone.

Answer

To solve the question, we need to understand the role of hormone receptors in the action of hormones on target organs. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understanding Hormone Action**: Hormones exert their effects on target organs by binding to specific receptors located on or within the target cells. These receptors are proteins that recognize and bind to specific hormones.

2. **Role of Receptors**: The binding of a hormone to its receptor initiates a series of biochemical events that lead to a physiological response in the target organ. Without these receptors, the hormone cannot exert its effect.

3. **Impact of Removing Receptors**: If the receptor molecules are removed from the target organ, the hormone will no longer have a binding site. Consequently, the hormone cannot interact with the target organ.

4. **Conclusion**: Since the hormone cannot bind to its receptor, the target organ will not respond to the hormone at all. Therefore, the correct answer to the question is that the target organ will not respond to the hormone.

### Final Answer:
The target organ will **not respond to the hormone** if the receptor molecule is removed.
