Will pepsin function at a pH 8?

Explanation

**Step-by-Step Solution:**

1. **Understanding Pepsin**: Pepsin is an enzyme that plays a crucial role in the digestion of proteins. It is classified as a protein-digesting enzyme, meaning it helps break down large protein molecules into smaller peptides.

2. **Optimal Conditions for Pepsin**: Enzymes, including pepsin, have specific conditions under which they function optimally. For pepsin, the optimal temperature is around 37 degrees Celsius, which is the average body temperature.

3. **pH Range for Pepsin Activity**: The activity of pepsin is highly dependent on pH. It functions best in highly acidic environments, specifically at a pH range of 1.5 to 2. This acidic environment is typically found in the stomach, where pepsin is secreted.
