Enzymes

Front

What are enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What happens to enzymes at high temperatures?

Back

The shapes of the enzyme are altered, which can lead to loss of function.

Front

What is the primary function of an enzyme?

Back

Enzymes speed up chemical reactions.

Front

What is meant by the 'optimum pH' of an enzyme?

Back

The optimum pH is the pH level at which an enzyme is most active.

Front

Do all enzymes have an optimal temperature and pH?

Back

Yes, every enzyme has an optimal temperature and pH for its activity.

Front

What are the main types of biological macromolecules?

Back

Proteins, nucleic acids, lipids, and carbohydrates.

Front

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

Back

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

Front

What is a substrate in the context of enzymes?

Back

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

Front

How do enzymes lower the activation energy of a reaction?

Back

Enzymes provide an alternative reaction pathway with a lower activation energy.

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like temperature or pH.
