Enzymes

Front

What is an enzyme?

Back

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

Front

What is the role of a substrate in enzyme activity?

Back

The substrate is the molecule upon which an enzyme acts.

Front

What is an active site?

Back

The region of an enzyme where the substrate binds.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed.

Front

What is the effect of temperature on enzyme activity?

Back

Enzymes have an optimal temperature range; too high or too low can reduce their activity.

Front

What is pH and how does it affect enzymes?

Back

pH is a measure of acidity or basicity; enzymes have optimal pH levels for activity.

Front

What is an inhibitor?

Back

A substance that can bind to an enzyme and prevent the substrate from binding.

Front

What is a coenzyme?

Back

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

Front

What is enzyme specificity?

Back

The concept that each enzyme only catalyzes a specific reaction with a particular substrate.

Front

What happens to enzymes at extreme pH levels?

Back

Extreme pH levels can denature enzymes, altering their structure and function.
