Front

What is the role of enzymes in biological reactions?

Back

To lower the activation energy and speed up the reaction.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it denatures.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.

Front

What is a substrate in the context of enzyme activity?

Back

The substance upon which an enzyme acts.
