Honors Bio-Enzymes

Front

What are toxins such as lead, pesticides, and mercury classified as?

Back

Irreversible inhibitors.

Front

Which chemical is classified as an enzyme?

Back

Protease.

Front

What are enzymes considered to be?

Back

Proteins.

Front

What is the primary purpose of an enzyme?

Back

To speed up reactions.

Front

What is it called when changes in pH and temperature damage an enzyme's active site?

Back

Denaturing.

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions.

Front

What is the role of the active site in an enzyme?

Back

It is the region where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate in the context of enzymes?

Back

The reactant molecule that an enzyme acts upon.

Front

What is the effect of temperature on enzyme activity?

Back

Increased temperature generally increases activity up to a point, after which denaturation occurs.

Front

What is the effect of pH on enzyme activity?

Back

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