Za ine Manganese
Manganese ndi yolimba, yolimba, yofiira-yenyezimira yomwe imapezeka ndi chitsulo. Ndi yofunikira kwa onse okalamba obadwa monga cofactor kwa ma enzyme ambiri. Oxygen-evolving complex mu photosystem II imagwiritsa ntchito manganese kuti ichepetse madzi.
Kugwiritsa ntchito & Maphunziro
Kupanga zitsulo, mabatire ouma, ma alloys a aluminiyamu, permanganate ya potaziyamu, ndi decolorizer ya glass.
Fun Facts
Manganese ndi chofunika kwambiri kwa photosynthesis - popanda izo, mbewu sizingathe kugawa madzi kuti apange oxygen timadzima.
