Why does only one specific substrate fit into an enzyme’s active site?

• Because the enzyme changes shape for every substrate

• Because the substrate and enzyme have matching shapes, like a lock and key

• Because substrates are all the same shape

Which of the following can affect how well an enzyme works?

• Temperature

• Color of the substrate

• Size of the enzyme

• Amount of light

• lock and key

• hammer and nail

• jigsaw puzzle

• seesaw

Why are enzymes considered reusable?

• Because they change permanently after helping a reaction

• Because they get used up after one reaction

• Because they are not changed and can help many reactions

What part of an enzyme does a substrate bind to?

• protein chain

• active site

• cell membrane

• ribosome

What happens to an enzyme after it helps convert a substrate into a product?

• It is used up and destroyed

• It changes into a different molecule

• It stays the same and can help other molecules.
