Manganese Superoxide Dismutase (MnSOD) - Chemistry …

Mitochondria are the location of many biological processes reducing O 2, producing an influx of O 2 ˙radicals. 1,3 The cofactor of the MnSOD protein is manganese (Mn). 1 The Mn changes between its 3+ and 2+ oxidation states within the dismutase mechanism, consisting of two half-reactions. 1 Electron exchange in metal complexes can happen by either an inner-sphere or outer-sphere mechanism.

Lightning - Wikipedia

Lightning is usually produced by cumulonimbus clouds, which have bases that are typically 1–2 km (0.62–1.24 mi) above the ground and tops up to 15 km (9.3 mi) in height. The place on Earth where lightning occurs most often is near the small village of Kifuka in the mountains of the eastern Democratic Republic of the Congo, [27] where the elevation is around 975 m (3,200 ft).
