Enzymes

Enzymes are an example of

• lipids

• carbohydrates

• protein

• nucleic acid

Each enzyme only has 1 substrate that will fit its active site.  What is this called?

• reusable

• catalyst

• fragile

• specific

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

What happens to an enzyme when it is denatured?

• Activation energy is lowered.

• It becomes stronger.

• It loses its shape.

• Activation energy is raised.
