Which of the following statements is/are wrong?

Options

A. Zeolites are hydrated aluminosilicates which can be used as shape-selective catalsts.
B. Enzymes show maximum activity when `pH` is either very low or very high.
C. Enzymes show maximum activity at room temperature `(20-25^(@)C)`
D. Chemically, all enzymes are globular proteins.

Explanation

To determine which statements are wrong, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option 1: Zeolites are hydrated alumino silicates which can be used as safe selective catalysts.**
- **Analysis**: This statement is true. Zeolites are indeed hydrated alumino silicates and they can act as shape-selective catalysts due to their porous structure. When zeolites are heated in a vacuum, they lose their water of hydration, which enhances their catalytic properties.
- **Conclusion**: This statement is **not wrong**.

2. **Option 2: Enzyme shows maximum activity when pH is either very low or very high.**
- **Analysis**: This statement is false. Enzymes typically have an optimal pH range where they exhibit maximum activity, which is often around neutral pH (approximately 7.4 for many enzymes). Extreme pH levels (very low or very high) usually denature enzymes, reducing their activity.
- **Conclusion**: This statement is **wrong**.

3. **Option 3: Enzyme shows maximum activity at room temperature 20 to 25 degrees Celsius.**
- **Analysis**: This statement is also false. Most enzymes in the human body have an optimal temperature around 37 degrees Celsius. While some enzymes may function at lower temperatures, the maximum activity is generally not at room temperature.
- **Conclusion**: This statement is **wrong**.

4. **Option 4: Chemically all enzymes are globular proteins.**
- **Analysis**: This statement is true. Enzymes are indeed proteins, and most enzymes are globular in shape, which is essential for their function as biological catalysts.
- **Conclusion**: This statement is **not wrong**.

### Final Conclusion:
The wrong statements are **Option 2** and **Option 3**.
