The right answer will recieve a brainlest and points and ! the right answer will recieve a brainlest and points and ! the hypothesis for the effect of ph on catalase activity as the ph of the buffer (increase or decrease), the amount of enzyme activity (increase or decrease) becasue

increase for both and

Enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH.  Extremely high or low pH values generally result in complete loss of activity for most enzymes.
