One effective method to denature catalase is to expose it to high temperatures, typically above 60°C, for a short period. This heat disrupts the hydrogen bonds and other interactions that maintain the enzyme's three-dimensional structure, leading to loss of its catalytic activity. Alternatively, adding strong acids or bases can also denature catalase by altering the pH and affecting its active site.
One method used to classify protozoa is by their method of locomotion. This can include cilia, flagella, or pseudopodia movement.
The catalase test can be used to distinguish quickly between Staphylococci and Streptococci in a gram-positive coccus isolated from a throat culture. Staphylococci are catalase positive (produce bubbles with hydrogen peroxide), while Streptococci are catalase negative (no bubble formation). This test can help differentiate between these two bacterial groups based on their enzyme activity.
Each catalase molecule can break down one molecule of hydrogen peroxide. Therefore, at least 10 catalase molecules would be needed to break down 10 molecules of hydrogen peroxide.

Because the shape of the active site on catalase only permits it to break down hydrogen peroxide. This is the case for many enzymes such as catalase, although some enzymes can break down more than one substrate.
Allow the temperature to go above that catalysts/enzymes operational temperature. e.g. Yeast works at about 37 oC, however, it denatures above 45 oC.
The turnover number for catalase is extremely high. One molecule of catalase can easily convert 400 million molecules of hydrogen peroxide to H2O.

One potential source of error in a catalase lab could be contamination of the catalase enzyme solution, which could lead to inaccurate results. Another source of error could be improper handling or storage of the catalase enzyme, affecting its activity. Additionally, variations in the temperature, pH, or substrate concentration during the experiments could introduce errors in the data collected.
