Malunga Manganese
I-manganese iyinsimbi eqinile, eqinile, emnyama-emnyama etholakala njalo nensimbi. Ibalulekile kuzo zonke izilwane eziphilayo njenge-cofactor ye-enzymes eziningi. I-oxygen-evolved complex kwi-photosystem II isebenzisa i-manganese ukuhlukanisa amanzi.
Izisebenziso
Ukukhiqizwa kwensimbi, amabhethri eselula emanzi, ama-alloys e-aluminium, i-potassium permanganate, kanye ne-glass decolorizer.
Iqiniso elijabulisayo
I-manganese ibalulekile ekusebenzeni kwe-photosynthesis -- ngaphandle kwayo, izitshalo azikwazi ukuhlukanisa amanzi ukuze zikhiqize i-oxygen esiyiphefumulayo.
