Front

How do enzymes speed up chemical reactions?

Back

Enzymes lower the activation energy of chemical reactions.

Front

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions without being consumed.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region where the substrate binds and the reaction occurs.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, losing their shape and function.

Front

What is substrate specificity?

Back

The ability of an enzyme to choose exact substrate from a group of similar chemical molecules.

Front

What is an allosteric site?

Back

A site on an enzyme where molecules can bind, changing the enzyme's activity.
