Reactants

Front

What is the term for the molecule upon which an enzyme acts?

Substrate

Front

What is the effect of temperature on enzyme activity?

Back

Increasing temperature generally increases enzyme activity up to a certain point, after which the enzyme may denature.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged and can catalyze subsequent reactions.

Inhibitor

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to a different site on the enzyme.

Front

What is the significance of enzyme specificity?

Back

Enzymes are specific to their substrates, meaning each enzyme only catalyzes a specific reaction.
