What are metalloenzymes? Explain catalase enzyme in details.
Understand the Problem
The question is asking for an explanation of metalloenzymes and specifically for detailed information about the catalase enzyme. This inquiry requires an understanding of biochemical concepts and the role of metal ions in enzyme function.
Answer
Metalloenzymes have metal ions for activity. Catalase, a metalloenzyme with heme, decomposes hydrogen peroxide to protect cells from damage.
Metalloenzymes are enzymes that contain one or more metal ions necessary for their biological activity. Catalase is a metalloenzyme containing heme groups, which play a crucial role in catalyzing the reaction that decomposes hydrogen peroxide into water and oxygen. Found abundantly in peroxisomes, catalase acts as a significant antioxidant, protecting cells from oxidative damage.

More Information
Catalase functions to decompose hydrogen peroxide, a harmful byproduct of metabolic reactions, thus protecting cells from oxidative stress. It is one of the fastest enzymes and helps maintain cellular health in aerobic organisms.
Tips
A common mistake is to confuse the role of catalase with catalysis of other substrates besides hydrogen peroxide. It's specifically involved in breaking down hydrogen peroxide.
