Focused Finish: Enzymes

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions by lowering the activation energy.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

True or False: Enzymes can act on many different substrates.

Back

False, enzymes are specific to their substrates.

Front

What is the purpose of an enzyme?

Back

To speed up chemical reactions.

Front

What is a substrate?

Back

Any substance that is acted upon by an enzyme.

Front

What is a base?

Back

A substance with a pH greater than 7.

Front

What is an active site?

Back

The region on an enzyme where the substrate binds.

Front

What is enzyme specificity?

Back

The concept that each enzyme only catalyzes a specific reaction for a specific substrate.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its shape and function due to extreme conditions.
