Pathogens that are catalase-positive, such as Mycobacterium tuberculosis, Legionella pneumophila, and Campylobacter jejuni, make
catalase in order to deactivate harmful peroxide radicals, thus allowing them to survive unharmed within the host cell. Which of the following are features of the catalase enzyme? a. endoenzyme
Catalase is an enzyme that is engaged during the the decomposition of hydrogen peroxide to form water and oxygen, it is posses by all living organisms because of their exposure to oxygen, hence it protect the cell from oxidative damage by reactive oxygen species.
Catalase enzymes function in our liver by breaking down harmful hydrogen peroxide into oxygen and water ,during this reaction , the bubbles of oxygen gas that escape create a foam that will help to disinfect any surface touch by the raw liver during this process. Catalase enzymes are extracellular enzyme and are inducible.
There are two kinds of food chains one starting with autotrophs, the grazing food chain, and the other starting with dead organic matter, the detrital food chain.
Plates at our planet's surface move because of the intense heat in the earth's core that causes molten rock in the mantel layer to move.It moves in a pattern called a convection cell forms when warm material rises,cools,and eventually sink down.
