Ph of catalase
WebThe following experiment is designed to see how pH levels affect the enzyme catalase process, (Daniel, Michelle, & Danson, 2010). In order to measure the outcome of the enzymatic reaction, this study will measure the acidic fluid and the procedure of the experiment. This experiment has been designed to clearly outline all directions and ways …

WebThe optimal pH level for human catalase is nearly 7. The optimal pH for other catalases fluctuates between 4-11 varying from species to species, same goes with the temperature parameter, it varies. Catalase Enzyme Function For the sustenance of life on earth, oxygen is pivotal. When the body uses oxygen, it constantly generates free radicals.
Web3. a. Since catalase is usually sensitive to pH variations and can be denatured or inactivated at extreme pH values, the addition of acid (HCI) is likely to reduce catalase activity. b. Since enzymes can be sensitive to variations in pH in the basic range, the addition of base (NaOH) may also reduce the activity of catalase. 4.
