Front

How do enzymes speed up reactions?

Back

By lowering the activation energy.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed.

Front

What is the role of the substrate in enzyme activity?

Back

The substrate is the reactant that an enzyme acts upon.

Front

What happens to an enzyme after a reaction?

Back

It can be reused for another reaction.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

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 may denature.
