Will pepsin function at a pH 8?

Explanation

**Step-by-Step Solution:**

1. **Understanding Pepsin**: Pepsin is a digestive enzyme that is primarily responsible for breaking down proteins into smaller peptides. It is secreted in an inactive form known as pepsinogen and is activated in the acidic environment of the stomach.

2. **Optimal pH for Pepsin**: Pepsin functions optimally in a highly acidic environment, with an ideal pH range of about 1.5 to 2. This acidic condition is crucial for its enzymatic activity.

3. **Effect of pH 8 on Pepsin**: At a pH of 8, which is alkaline, pepsin will not function effectively. The enzyme's structure and active site are altered in such a basic environment, leading to a loss of its catalytic activity.
