Which is wrong about enzymes

Options

A. Enzymes are mostly proteins but some are lipids also
B. Enzymes are highly specific
C. Enzymes require optimum pH and temperature for maximum activity
D. Enzymes are denatured at high temperature.

Answer

To determine which statement about enzymes is incorrect, we will analyze each option provided in the question one by one.

### Step-by-Step Solution:

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in the body. They are primarily proteins.

2. **Analyzing the Statements**:
- **Statement 1**: "Enzymes are mostly proteins but some are lipids also."
- **Analysis**: This statement is incorrect. All enzymes are proteins; there are no enzymes that are lipids. Therefore, this is the wrong statement.

- **Statement 2**: "Enzymes are highly specific."
- **Analysis**: This statement is true. Each enzyme is specific to a particular substrate, meaning it only catalyzes a specific reaction.

- **Statement 3**: "Enzymes require optimum pH and temperature for maximum activity."
- **Analysis**: This statement is also true. Enzymes function best at specific pH levels and temperatures, which vary for different enzymes.

- **Statement 4**: "Enzymes are denatured at high temperature."
- **Analysis**: This statement is true as well. High temperatures can lead to the denaturation of enzymes, breaking the bonds that maintain their structure.

3. **Conclusion**: After analyzing all the statements, the only incorrect statement is the first one: "Enzymes are mostly proteins but some are lipids also."

### Final Answer:
The wrong statement about enzymes is: **"Enzymes are mostly proteins but some are lipids also."**
