Why has this enzyme activity decreased so much?

• The enzyme has become saturated

• The temperature is too low

• The enzyme has become denatured

What happens when an enzyme denatures?

• The enzyme becomes overused

• The substrate has run out

• The primary structure of the protein ahs changed

• The secondary/tertiary structure of the protein has changed

What happens to the pepsin enzyme in alkaline conditions

• The reaction rate increases

• The enzyme collides with more substrate

• The enzyme will denature and no longer work

• The shape of the enzyme does not change and still has activity

• Competitive inhibition

Which of the following can be used to determine the rate of enzyme-catalyzed reactions?

• Rate of disappearance of the enzyme

• Rate of disappearance of the substrate

• Rate of disappearance of the product

• Change in volume of the solution
