What factors affect enzyme activity?

What factors affect enzyme activity?

Enzyme activity can be influenced by several factors, including temperature, pH, substrate concentration, and enzyme concentration.

How does temperature affect enzyme activity?

Temperature affects enzyme activity by altering the enzyme's shape. Generally, higher temperatures increase activity up to a point, after which the enzyme may denature.

What is the optimal pH for most enzymes?

Most enzymes have an optimal pH around 7, but some, like pepsin, work best in acidic conditions, while others prefer alkaline.

Can enzyme concentration affect the reaction rate?

Yes, increasing enzyme concentration typically increases the reaction rate, provided there is enough substrate available.

What happens if the substrate concentration is too high?

If substrate concentration is too high, the reaction rate will plateau because all active sites on the enzyme molecules are occupied.
