Homework Answers
Ans . Each enzyme has its own optimal range of pH in which it's work effectively. Catalase works between pH 7 to pH 11. If the pH level is lower than 7 or higher than 11, the enzyme becomes denaturated and loses its structure.
Enzyme pH levels also change the shape of the active site and affect the rate of enzyme activity.
so the correct answer is denature (breakdown / change the shape of) the enzyme.

Enzyme Activity (ml) Effect of pH on (amylase) enzyme activity. For determination of optimum assay pH of the enzyme reaction, 0.05 M Na2HPO4-NaH2PO4 buffer was used. The reaction was carried out for 10 min at 50°C in a shaking water. The enzyme activity was measured and the results are presented on graph, Bars represent means standard deviations for three replicates. 1. What do the error bars in this graph represent?...
