Options

A. Agonists
B. Antagonists
C. Co-factors
D. Allosterics

Answer

To solve the question "Drugs that bind to the receptor site and inhibit its natural function are called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the term used to describe drugs that bind to receptor sites and inhibit their natural function.

2. **Define Key Terms**:
- **Receptor Site**: A specific location on a cell where a drug or other substance can bind to exert its effect.
- **Inhibit**: To prevent or hinder the function of something.

3. **Identify Drug Types**:
- There are different types of drugs that interact with receptors, including agonists and antagonists.
- **Agonists**: These drugs bind to receptors and activate them, mimicking the action of a natural substance.
- **Antagonists**: These drugs bind to receptors but do not activate them. Instead, they block or inhibit the receptor's natural function.

4. **Select the Correct Answer**: Since the question specifically asks for drugs that inhibit the receptor's natural function, the correct term is "Antagonists."

5. **Final Answer**: Therefore, the answer to the question is that drugs that bind to the receptor site and inhibit its natural function are called **Antagonists**.
