Enzymes

Front

What are reactants in a chemical reaction?

Back

Substances that are changed during a chemical reaction.

Front

What happens to enzymes when they are heated to a high temperature?

Back

The shape of the enzyme is changed and it denatures.

Front

What is the enzyme-substrate complex?

Back

It is the intermediate formed when an enzyme binds to its substrate.

Front

How do enzymes speed up reactions?

Back

By lowering the activation energy required for the reaction.

Front

What occurs when an enzyme is denatured?

Back

It loses its shape and can no longer function.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

What are products in a chemical reaction?

Back

Substances that are produced as a result of a chemical reaction.

Front

What is the role of enzymes in biological systems?

Back

To catalyze biochemical reactions, making them occur faster.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

What is enzyme specificity?

Back

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