Inhibition of enzyme action due to acculumation of end products is called

Options

A. Competitive inhibition
B. Non competitive inhibition
C. Feedback inhibit on
D. Metabolic inhibition

Answer

To solve the question about the inhibition of enzyme action due to the accumulation of end products, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about a specific type of enzyme inhibition that occurs when the end products of a reaction accumulate.

2. **Identify the Options**: The options provided are:
- A) Competitive inhibition
- B) Non-competitive inhibition
- C) Feedback inhibition
- D) Metabolic inhibition

3. **Define Each Option**:
- **Competitive Inhibition**: This occurs when a substance competes with the substrate for the active site of the enzyme.
- **Non-competitive Inhibition**: This occurs when an inhibitor binds to an enzyme at a site other than the active site, changing the enzyme's shape and function.
- **Feedback Inhibition**: This is a regulatory mechanism where the end product of a metabolic pathway inhibits an enzyme involved in its synthesis, preventing overproduction.
- **Metabolic Inhibition**: This is a broader term that can refer to various forms of inhibition in metabolic pathways.

4. **Analyze the Correct Answer**: The key phrase in the question is "accumulation of end products." Feedback inhibition specifically refers to the process where the end product of a reaction pathway inhibits an earlier step in the pathway, thus regulating the production of that product.

5. **Conclusion**: Based on the definitions and the analysis, the correct answer is **C) Feedback inhibition**.

### Final Answer:
The inhibition of enzyme action due to accumulation of end products is called **feedback inhibition**.
