where do you find catalase in the body
Catalase The large majority of known organisms use catalase in every organ, with particularly high concentrations occurring in the liver in mammals.[29] One unique use of catalase occurs in the bombardier beetle. This beetle has two sets of liquids that are stored separately in two paired glands. The larger of the pair, the storage chamber or reservoir, contains hydroquinones and hydrogen peroxide, while the smaller, the reaction chamber, contains catalases and peroxidases. To activate the noxious spray, the beetle mixes the contents of the two compartments, causing oxygen to be liberated from hydrogen peroxide. The oxygen oxidizes the hydroquinones and also acts as the propellant.[30] The oxidation reaction is very exothermic (ΔH = −202.8 kJ/mol) and rapidly heats the mixture to the boiling point.[31]
Grumpy Cat Tardar Sauce was one of a litter of four kittens born to a calico mother and a father of an unknown breed at the home of her owner, Tabatha Bundesen.[6][7] The Bundesens say that Tardar Sauce's face appears grumpy because the feline has a form of dwarfism. She and her brother Pokey were born to normal parents with "a flat face, bubble eyes, and a short tail".[8] Tardar Sauce is undersized and has hind legs that "are a bit different".[2][4] Although she has a "grumpy" appearance and is called "Grumpy Cat", according to the Bundesens, 99% of the time she is a "normal kitty".[2][4][9]
