Enzymes

Front

What is an enzyme?

Back

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

Front

What is the primary function of enzymes?

Back

To speed up chemical reactions by lowering the activation energy required.

Front

What do enzymes typically end with?

Back

-ase

Front

What happens to enzymes at high temperatures?

Back

They can denature, meaning their shape is altered and they may lose functionality.

Front

What is denaturation in the context of enzymes?

Back

The process where the enzyme's structure is altered, affecting its function.

Front

Do enzymes have an optimal temperature and pH?

Back

Yes, each enzyme has specific conditions under which it works best.

Front

What is the effect of pH on enzyme activity?

Back

Extreme pH levels can denature enzymes, reducing their activity.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate in relation to enzymes?

Back

The substance on which an enzyme acts.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy needed for a reaction to occur.
