How does pH affect catalase enzyme activity?
Herein, how does the pH affect enzyme activity?
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. pH is also a factor in the stability of enzymes.
Also Know, how does enzyme concentration affect catalase activity? This maximum is known as the temperature optimum of the enzyme. Substrate concentration: The amount of substrate will affect the rate of reaction- as substrate concentration increases, rate of reaction will increase proportionally until all the enzymes are saturated, then it will level off.
Similarly, you may ask, which pH is best for catalase activity?
approximately pH 7.0
What is the pH of catalase?
It is a tetramer of four polypeptides chains containing four porphyrin heme groups that allow the enzyme to react with the hydrogen peroxide. The optimum PH of human catalase is approximately 7 and the optimum temperature is at 37 degree.
