4 - Enzyme

Front

What happens to an enzyme when it is exposed to extreme pH levels?

Back

The enzyme will denature, meaning it loses its functional shape.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds.

Front

What are enzymes primarily made of?

Back

Enzymes are primarily made of proteins.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its shape and functionality due to external factors like heat or pH.

Front

What factors can lead to enzyme denaturation?

Back

Excessive heat and changes in pH can lead to enzyme denaturation.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts, lowering the activation energy needed for reactions to occur.

Front

How do enzymes affect the speed of chemical reactions?

Back

Enzymes increase the speed of chemical reactions by lowering the activation energy.

Front

What is a substrate in relation to enzymes?

Back

A substrate is the reactant that binds to the enzyme's active site.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.

Front

What happens to the enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged and can catalyze another reaction.
