3.2 Enzymes

Front

What is the purpose of an enzyme?

Back

To speed up reactions.

Front

Can an enzyme be used again?

Back

Yes.

Front

Can an enzyme work with any substrate?

Back

No.

Front

What happens when enzymes are heated to a high temperature?

Back

The shapes of the enzyme are altered (denatured).

Front

What is a substrate in the context of enzymes?

Back

The substance on which an enzyme acts.

Front

What is enzyme specificity?

Back

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

Front

What is denaturation in enzymes?

Back

The process in which an enzyme loses its functional shape due to high temperature or pH changes.

Front

What factors affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

What is the role of cofactors in enzyme activity?

Back

Cofactors are non-protein molecules that assist enzymes in catalyzing reactions.
