What happens when enzymes are heated to a high temperature?

• The enzymes die.
• The shapes of the enzyme are altered or denatured
• The enzymes' amino acid sequence changes.
• The enzymes remain the same

The diagram represents one way an enzyme can be inhibited.

Which statement explains the effect of an inhibitor on an enzyme?
