Enzymes Lesson

What happens to an enzyme when it is denatured?

• Activation energy is lowered

• It becomes stronger

• It loses its shape

• Activation energy is raised

What happens when enzymes are heated to a high temperature?

• The enzymes die.

• The shape of the enzyme are changed and it denatures

• The enzymes' amino acid sequence changes.

• The enzymes remain the same
