Respuesta :
The impact of pH on activity takes into account that catalase will be negatively impacted by both low and high pH solutions.
What is catalase ?
All aerobic organisms have the antioxidant enzyme catalase (CAT, 1.11.1.6). In cells subjected to environmental stress, it is known may catalyze Hâ‚‚Oâ‚‚ into oxygen and water in an energy-efficient manner. A common catalase, which is found in nearly all living organisms exposed to oxygen, converts hydrogen peroxide into water and oxygen. It is an essential enzyme for protecting the cell from oxidative damage caused by reactive oxygen species.
What is the function of a catalase?
The important enzyme catalase feeds on peroxide, a non - radical ROS. This enzyme is in charge of neutralizing hydrogen peroxide through its breakdown, hence preserving an ideal level of a molecules in the cell that is also necessary for cellular signalling processes.
Explanation:
The activities of catalase is adversely affected by both low and high pH solutions. The pH level of 7 produced the fastest rate. The catalase was more affected by the acidic, low pH solution, resulted in no chemical response at all. An acidic solution produces an overabundance of H+ ions at the molecular level.
The ideal pH for catalase is 9, and its practical operating range is between pH 7 and pH 11. Most other enzymes operate best at a neutral pH of 7, with a functioning pH range of roughly 5 to 9.
