[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
The enzymes of H2O2catabolism present in peroxisomes are
|
|
Sulfuric Acid and Peroxidase
|
|
|
Peroxidase and Catalase
|
|
|
Oxidase and Peroxidase
|
|
|
Catalase and Oxidase
|
Explanation:
Detailed explanation-1: -Therefore, peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen, thereby neutralizing the toxicity.
Detailed explanation-2: -Peroxisomes contain at least 50 different enzymes, which are involved in a variety of biochemical pathways in different types of cells. Peroxisomes originally were defined as organelles that carry out oxidation reactions leading to the production of hydrogen peroxide.
Detailed explanation-3: -Catalase-peroxidase (KatG)4 is a bifunctional heme-dependent enzyme found in bacteria and lower eukaryotes (1), which is integral to the defense of these organisms against H2O2 toxicity (2, 3).
