What do enzymes do to activation energy?

Back

Enzymes lower the activation energy to speed up chemical reactions.

Front

What type of biological macromolecule are enzymes?

Back

Enzymes are a type of protein.

Front

At what temperature do most enzymes have optimal activity?

Back

Most enzymes have optimal activity around 35 degrees Celsius.

Front

Why are enzymes crucial in biological processes?

Back

Enzymes are important because they speed up chemical reactions.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes act as catalysts in chemical reactions.

Front

What is a catalyst?

Back

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

Front

What happens to enzyme activity at extreme temperatures?

Back

Extreme temperatures can denature enzymes, reducing their activity.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can decrease activity.

Front

Can enzymes be reused after a reaction?

Back

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

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind.
