Enzymes generally have different pH but same temperature optima.

Explanation

**Step-by-Step Solution:**

1. **Understanding Enzyme Functionality:**
Enzymes are biological catalysts that speed up chemical reactions in the body. They work by binding to substrates and converting them into products.

2. **pH Optima of Enzymes:**
Different enzymes have different optimal pH levels at which they function best. For example:
- Pepsin, an enzyme found in the stomach, works optimally at a highly acidic pH of around 2.5.
