What happens to an enzyme when it is denatured?

Back

It loses its shape.

Front

What is the role of enzymes in biochemical reactions?

Back

To lower the activation energy required for the reaction.

Front

What is a substrate in the context of enzyme activity?

Back

The specific reactant that an enzyme acts upon.

Front

What is meant by enzyme specificity?

Back

Enzymes are specific to their substrates and only catalyze specific reactions.
