Enzymes

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

What is the substrate in an enzymatic reaction?

Back

The molecule upon which an enzyme acts.

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where the substrate binds.

Front

What is the enzyme-substrate complex?

Back

The temporary complex formed when an enzyme binds to its substrate.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for reactions, making them occur more easily.

Front

What is the role of coenzymes?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions.

Front

What is an allosteric site?

Back

A site on an enzyme where molecules can bind, causing a change in the enzyme's activity.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, losing their shape and functionality.

Front

What is enzyme specificity?

Back

The concept that each enzyme only catalyzes a specific reaction or type of reaction.
