How does pH affect enzyme activity?

How does pH affect enzyme activity?

pH levels can significantly influence enzyme activity by altering their structure and function. Each enzyme has an optimal pH range.

What happens if the pH is too high or too low?

If the pH is too high or too low, enzymes can denature, losing their shape and functionality, which decreases reaction rates.

Can you give an example of an enzyme that is sensitive to pH?

Sure! Pepsin, an enzyme in the stomach, works best at a highly acidic pH of around 1.5 to 2.

Are there any enzymes that work well in alkaline conditions?

Yes, for example, trypsin functions optimally in alkaline conditions, around pH 7.5 to 8.5.

How can we measure the effect of pH on enzyme activity?

You can measure enzyme activity by conducting experiments that assess reaction rates at different pH levels, using substrates and measuring product formation.
