Enzymes

Front

What happens when enzymes are heated to a high temperature?

Back

The shapes of the enzyme are altered and they denature.

Front

True or False: Every enzyme has an optimal temperature and pH.

Back

True.

Front

What is the purpose of an enzyme?

Back

To speed up reactions.

Front

What is the term for the specific region on an enzyme where the substrate binds?

Back

Active site.

Front

Enzymes are an example of which type of biological macromolecule?

Back

Protein.

Front

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

Back

Substrate.

Front

What effect does a high temperature have on enzyme activity?

Back

It can denature the enzyme, reducing its activity.

Front

What is the role of enzymes in biochemical reactions?

Back

They lower the activation energy required for reactions.

Front

What is meant by 'enzyme specificity'?

Back

Enzymes are specific to particular substrates due to their unique active sites.

Front

What can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.
