Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

What is the active site of an enzyme?

Back

The specific region on an enzyme where the substrate binds and the reaction occurs.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape changes and they lose their functionality.

Front

What is a competitive inhibitor?

Back

A substance that competes with the substrate for binding to the active site of an enzyme, slowing down the reaction.

Front

What is an endothermic reaction?

Back

A reaction that absorbs energy from its surroundings.

Front

What is the role of temperature in enzyme activity?

Back

Temperature affects the rate of enzyme activity; too high or too low temperatures can denature enzymes or slow down reactions.

Front

What is pH's effect on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.

Front

What are substrates?

Back

The reactants that enzymes act upon during a chemical reaction.

Front

What are products in an enzymatic reaction?

Back

The substances that are produced as a result of the enzymatic reaction.
