Enzymes EOC review

Front

What is hydrolysis?

Back

Hydrolysis is a chemical reaction in which water is used to break down a compound, typically involving the splitting of a bond in the presence of water.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that involves the removal of water to form a bond between two molecules, creating a larger compound.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions without being consumed in the process.

Front

What is an active site?

Back

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

Front

What happens to an enzyme after it catalyzes a reaction?

Back

After catalyzing a reaction, an enzyme can be reused for another reaction with the same reactants.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process in which an enzyme's structure is altered, causing it to lose its functional shape and, therefore, its activity.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations from this range can lead to denaturation and loss of activity.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is a substrate?

Back

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

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases or prevents the activity of an enzyme.
