What converts free radicals to hydrogen peroxide in a cell?

Specifically peroxidase, the enzyme that resides in the peroxisomes.


What converts super oxide free radical into hydrogen peroxide?

Superoxide dismutase is the enzyme that converts superoxide free radicals into hydrogen peroxide by catalyzing the dismutation (splitting) of two superoxide ions into oxygen and hydrogen peroxide.


How is hydrogen peroxide antimicrobial?

Hydrogen peroxide is antimicrobial because it generates free radicals, such as hydroxyl radicals, which are highly reactive and can damage the cell membranes, proteins, and DNA of microorganisms, leading to their disruption and death. It has broad-spectrum antimicrobial activity against bacteria, viruses, fungi, and spores.


Why is water harmless and hydrogen peroxide is poisionous given that both are compounds of hydrogen and oxygen?

The difference lies in their chemical structures and compositions. Hydrogen peroxide is a highly reactive compound with an additional oxygen atom compared to water, making it unstable and capable of releasing harmful free radicals. This reactivity is what causes hydrogen peroxide to be toxic when ingested or applied to the skin, while water, with its stable H2O composition, is essential for life and generally harmless.


What is the role of benzoyl peroxide in polymerisation of ethene?

Acts as a chain intiatoor by breaking into two benzoyl chloride free radicals (homolytic cleavage) and then involves itself in chain propoogation step after breaking free in the initial step known as the chain initiation step.

How could you produce hydroxyl free radicals?

Hydroxyl free radicals can be produced through the Fenton reaction, which involves the reaction of hydrogen peroxide with ferrous ions to generate hydroxyl radicals. Another method is through the photolysis of water, where sunlight splits water molecules into hydroxyl radicals.


What is a catalase?

Hello there! Catalase is a common enzyme found in organisms exposed to oxygen. It plays an important role in speeding up or catalysing, decomposition of hydrogen peroxide into oxygen and hydrogen. In this way, the enzyme protects you from the damage of free radicals like hydrogen peroxide. Hopefully, this helped you! 😊👍


What is the job of the catalase enzyme?

Catalase breaks down toxic hydrogen peroxide in living organisms (in both plants and animals) into water and oxygen. 2H2O2 (reaction of catalase) produces 2H2O + O2

What are some examples of free radicals?

Hydrogen Peroxide is an example of a free radical. A free radical works by causing the oxidation of another atom. Free radicals are highly reactive because they are missing an electron. They will take that electron from any plant, human, or animal atom in a cell. That atom is then missing an electron and becomes a free radical itself. When any compound has the suffix -oxide in it, that usually hints that it is a free radical and would be considered basic on the pH scale.


Which disinfectant does not act by disrupting the plasma membrane?

Hydrogen peroxide is a disinfectant that does not primarily act by disrupting the plasma membrane. Instead, it exerts its antimicrobial effects by generating free radicals that damage intracellular components and disrupt cellular function.

What cell organelle possesses oxidise enzymes that function in neutralizing harmful free radicals?

The cell organelles that possess oxidase enzymes that function in neutralizing harmful free radicals are the peroxisomes. They are also known as microbodies and can be found in almost all eukaryotic cells.


Is hydrogen peroxide a good conductor of electricity?

Hydrogen peroxide is a poor conductor of electricity as it is a non-metallic compound that does not dissociate into ions in solution. It does not contain free ions that can carry an electric current.
