Front

True or False: Enzymes are used to break down the food we eat.

Back

TRUE

Front

What are the products of an enzyme-catalyzed reaction?

Back

Substances formed after the reaction.

Front

What is the role of enzymes in biological systems?

Back

To catalyze biochemical reactions, increasing their rate.

Front

What is a substrate in the context of enzyme activity?

Back

The reactant molecule that an enzyme acts upon.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity typically increases with temperature up to an optimal point, then decreases.

Front

What happens to enzymes at extreme pH levels?

Back

They can denature, losing their functional shape.
