Ans) Iron is important cofactor for both bacterial and human chemical reactions.
Explainations: Siderophores are special chelating agent that are released by bacteria and they have high affinity for iron so they compete with host cell for iron and provide iron to bacterial cell and helps in its pathogenecity as iron function as important cofactor in various chemical reactions in both bacteria and human but it make iron available to bacteria and depried human host cell from iron .

which statement about iron uptake into bacterial cells is FALSE? a) siderophores bind ferric iron b) bacteria can have receptors for siderophores that they themselves do not make c) in a form of nutritional immunity, human cells compete for iron in order to prevent iron uptake d) ferric iron is extremely soluble, and this is why there is a fierce competition for it in nature

Most commonly known for its ability to bind to oxygen, iron also plays the important role of acting as a cofactor oxidation-reduction reactions. to many enzymes in numerous Red blood cells without iron become pale and this is called hypochromic. In individuals with lighter skin, this also results in a distinct pale appearance called_pallor . Vegans, vegetarians, and those following a variety of plant-based diets can get enough iron from their diet from eating foods that contain chloro- iron along...
