For example, pepsin, an enzyme in the stomach, has an optimal pH of around 2, which is acidic. In contrast, enzymes in the small intestine, such as pancreatic amylase, have an optimal pH around 7-8, which is slightly alkaline. Maintaining the appropriate pH is crucial for enzymes to maintain their structure and catalytic activity. **
