What happens if an enzyme's shape is altered?

• It becomes more effective

• It can no longer bind to its substrate

• It can bind to any substrate

• It becomes a different enzyme

What happens if an enzyme's shape is changed?

• It becomes more colorful

• It works faster

• The substrate will no longer fit in the active site

• It becomes larger

What is the effect of a pH level that is too low or too high on an enzyme?

• It enhances enzyme activity

• It has no effect

• It makes the enzyme glow

What happens when an inhibitor binds to an enzyme?
