Enzyme and Macromolecules Test CP

Front

What are two factors that can affect an enzyme's ability to function?

Back

Temperature and pH.

Front

What is the role of an enzyme in a chemical reaction?

Back

An enzyme speeds up a reaction by lowering the activation energy.

Front

What is a substrate in the context of enzyme activity?

Back

Any substance that is acted upon by an enzyme.

Front

What does a substrate become after an enzyme catalyzes a reaction?

Back

A product.

Front

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

Back

Active site.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

It can be reused for another reaction.

Front

What is the effect of temperature on enzyme activity?

Back

Enzymes have an optimal temperature range; too high or too low can denature the enzyme.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH; deviations can reduce activity or denature the enzyme.

Front

What is a coenzyme?

Back

A non-protein molecule that assists enzymes in catalyzing reactions.

Front

What is the difference between an enzyme and a substrate?

Back

An enzyme is a catalyst that speeds up reactions, while a substrate is the substance being acted upon.
