Enzymes

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What do enzymes typically end with?

Back

-ase

Front

What is the role of a substrate in enzyme activity?

Back

A substrate is the substance upon which an enzyme acts.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape is altered and they can no longer function.

Front

What is the optimal pH range for most enzymes?

Back

Most enzymes function best at a neutral pH of around 7.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where the enzyme's structure is altered, affecting its function.

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 coenzyme?

Back

An enzyme is a protein that catalyzes reactions, while a coenzyme is a non-protein helper.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors.

Front

What is an inhibitor in enzyme activity?

Back

A substance that decreases the activity of an enzyme.
