Enzyme Quick Check

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where substrates bind and undergo a chemical reaction.

Front

Where do substrates bind on an enzyme?

Back

Substrates bind at the active site of the enzyme.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy.

Front

What does specificity mean in the context of enzymes?

Back

Specificity refers to the ability of an enzyme to recognize and bind to a specific substrate.

Front

What happens to enzymes at high temperatures or extreme pH levels?

Back

Enzymes become denatured, losing their functional shape and activity.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes facilitate biochemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is a substrate?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is denaturation in enzymes?

Back

Denaturation is the process by which an enzyme loses its three-dimensional structure, rendering it inactive.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect the rate of a chemical reaction?

Back

Enzymes increase the rate of a chemical reaction by lowering the activation energy.
