What is a substance called if it speeds up a chemical reaction?

Back

A catalyst.

Front

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

Back

The shape of the enzyme changes and it denatures.

Front

What is the primary function of an enzyme?

Back

Enzymes speed up chemical reactions.

Front

In the enzyme-substrate model, what does the substrate turn into at the end of the chemical reaction?

Back

Products.

Front

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

Back

Active site.

Front

What is the effect of pH on enzyme activity?

Back

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

Front

What is enzyme specificity?

Back

Enzymes are specific to particular substrates due to their unique active sites.

Front

What are coenzymes?

Back

Non-protein molecules that assist enzymes in catalyzing reactions.

Front

What is the role of temperature in enzyme activity?

Back

Temperature affects the rate of enzyme activity; too high or too low can denature the enzyme.

Front

What is enzyme inhibition?

Back

A process where a molecule reduces or stops enzyme activity.
