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. Most enzymes have an optimal temperature range where they function best.

What happens if the temperature is too high?

If the temperature is too high, enzymes can denature, losing their shape and functionality, which decreases their activity.

Can pH levels also affect enzyme activity?

Yes, pH levels can significantly affect enzyme activity. Each enzyme has an optimal pH range, and deviations can reduce activity.

What is substrate concentration's role in enzyme activity?

Substrate concentration affects the rate of reaction; as substrate concentration increases, the reaction rate increases until it reaches a maximum.
