Does pH have any effect on enzymes ?

Explanation

### Step-by-Step Solution

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are proteins that have specific structures which allow them to perform their functions effectively.

2. **Role of pH**: pH refers to the acidity or alkalinity of a solution. It is measured on a scale from 0 to 14, where 7 is neutral, below 7 is acidic, and above 7 is basic. Enzymes are sensitive to changes in pH.

3. **Optimum pH**: Each enzyme has an optimum pH at which it functions best. This is the pH level where the enzyme's activity is maximized. For many human enzymes, this optimum pH is around 7, which is neutral.
