AP Bio Insta-Review Topic 3.3: Environmental Impacts on Enzyme

Front

What happens to an enzyme if the temperature increases too high?

Back

Enzyme denatures.

Front

As pH increases, what happens to the hydrogen ion concentration?

Back

Decreases.

Front

As the product concentration increases, what happens to the reaction rate?

Back

Decreases.

Front

What is a competitive inhibitor?

Back

Binds to the same site as the substrate.

Front

When an enzyme denatures, which structure is not affected?

Back

Primary structure.

Front

What is the optimal temperature range for most enzymes?

Back

Typically between 30°C and 40°C.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to denaturation.

Front

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

Back

To lower the activation energy and increase the reaction rate.

Front

What is an allosteric site?

Back

A site on an enzyme where a molecule can bind, affecting enzyme activity.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to an allosteric site.
