ስለ Manganese
Manganese is a hard, brittle, silvery-gray metal often found with iron. It is essential for all living organisms as a cofactor for many enzymes. The oxygen-evolving complex in photosystem II uses manganese to split water.
ፕሮግራሞች
Steel production, dry cell batteries, aluminum alloys, potassium permanganate, and glass decolorizer.
ሐቅ
Manganese is essential for photosynthesis -- without it, plants could not split water to produce the oxygen we breathe.
