What is the significance of SOD and catalase to the pathogenesis of bordetella pertussis?
SOD converts the dangerous superoxide radical to hydrogen peroxide, which catalase converts to harmless water and oxygen. Catalases are some of the most efficient enzymes found in cells; each catalase molecule can convert millions of hydrogen peroxide molecules every second.
The activity of which organelle helps keep the ingestion of all but excessive amounts of ethyl alcohol from being fatal?
Peroxisomes hold enzymes that digest amino acids, fatty acids, and hydrogen peroxide, a toxic metabolic product. Enzymes convert hydrogen peroxide to water and oxygen or use it in reactions that degrade alcohol and other toxins. Drink alcohol, and peroxisomes in liver and kidney cells usually degrade nearly half of it.
What chemical reaction does the enzyme called catalse facilitate?
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen.It is a very important enzyme in reproductive reactions. Likewise, catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second.The reaction of catalase in the decomposition of living tissue:2H2O2 → 2H2O + O2The presence of catalase in a microbial or tissue sample can be tested by adding a volume of hydrogen peroxide and observing the reaction. The formation of bubbles, oxygen, indicates a positive result. This easy assay, which can be seen with the naked eye, without the aid of instruments, is possible because catalase has a very high specific activity, which produces a detectable response.
Chemical makeup of bleach?
Colored substances contain molecules with chromophores, areas of the molecule that have double bonds between carbon atoms or oxygen atoms. A good example is beta carotene, and that section goes into more detail on how molecules become colored. Bleaches attack these chromophores in one of two ways. Oxidizing bleaches like sodium hypochlorite break the molecules at the double bond. This results in either a shorter molecule that does not absorb visible light, or a molecule whose chromophore is either shorter or non-existant. A shorter chromophore will absorb light of a shorter wavelength than visible light (such as ultraviolet light), and so does not appear colored. Reducing bleaches such as lemon juice (in combination with sunlight) or sulfur dioxide, convert the double bonds in the chromophore into single bonds, eliminating its ability to absorb visible light. Sometimes the reaction is reversible, where oxygen in the air reacts with the molecule to repair the chromophore, and the stain returns. Another chlorine bleach often used is sodium dichloroisocyanurate. Oxygen bleaches also work by releasing oxygen. Hydrogen peroxide is the active ingredient, either as itself, or as a product of reacting another ingredient with water to release hydrogen peroxide. Oxygen bleaches such as sodium carbonate peroxide (also called sodium percarbonate), sodium peroxide, or sodium perborate are made by reacting molecules with hydrogen peroxide. When the result is added to water, the hydrogen peroxide is released. Borax also works by releasing hydrogen peroxide into the water. Most oxygen bleaches work best in hot water. Additives such as tetra acetyl ethylene diamine allow the hydrogen peroxide to work in warm water (50° C).
Does nuclear fusion convert oxygen to hydrogen?
No. Nuclear fusion will convert hydrogen to helium and, at higher temperatures, oxygen into silicon, phosphorus, and sulfur.
Which organelle can convert hydrogen peroxide into two harmless products?
Catalase is an enzyme produced by the liver which can break down hydrogen peroxide into oxygen and water...Does that answer your question?

How is hydrogen peroxide broken down?
Peroxisomes are organelles that has an enzyme called catalase. This enzyme breaks down a harmful substance like hydrogen peroxide in cells to convert it into oxygen and water, which are harmless products.
What is the turnover number for catalase?
The turnover number for catalase is extremely high. One molecule of catalase can easily convert 400 million molecules of hydrogen peroxide to H2O.
Why does hydrogen peroxide bubbled?
Hydrogen Peroxide H2O2 is chemically unstable, and exposure to a catalyst will cause it to convert into Oxygen Gas and Water. The bubbles are Oxygen Gas. The equation that describes this change is 2H2O2 ---> O2 + 2H2O Even light, heat or age can trigger this decomposition reaction.
How do you convert Silver oxide back to silver?
To properly dispose of Silver Oxide :• Add 100 volumes of distilled water to 1 volume Silver Oxide powder. (glass container only)• Add common household Hydrogen Peroxide, very slowly, with lots of stirring. (glass or plastic stirrer only)• Add Hydrogen Peroxide, stirring, until all of the Black Powder has turned gray. (lots of bubbles - Oxygen)• You now have reduced Silver Oxide into harmless Silver Powder. (You may want to keep it)• NOTE : Silver Powder also breaks down the Hydrogen Peroxide, forming Oxygen bubbles.
Does the liver convert toxic ammonia into harmless urea?
Yes.
What does nuclear fusion convert hydrogen into?
Nuclear reactions in the cores of stars convert hydrogen to helium

What is a unique property of water Describe the property and explain the chemical or physical reason that causes water to have the property?
Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
Why does hydrogen fluoride have a higher boiling point than hydrogen chloride?
The small size and high electronegativity of Fluorine is responsible for high polarity in HF molecules this high polarity is responsible for strong hydrogen bonding with in HF molecules so high amount of heat is required to convert the liquid HF into gaseous state and hence it has high boiling point as compare to HCl.Polar.
