Answer:
pH level changes the shape and affects the rate of activity of the enzyme.
Explanation:
Catalase, in humans only works between pH 7 to pH 11, anything lower, it denatures and loses its structure.
ph less than 4 and more than 10, rate of catalase activity reduced. optimum temperature for is 30 degree celcius less than 5 and more than 50 degree celcius enzyme activity starts to reduce due to denaturation.
