Web4 jul. 2024 · Metabolic processes use NADH and [FADH 2] to transport electrons in the form of hydride ions (H - ). These electrons are passed from NADH or [FADH 2] to membrane bound electron carriers which are then passed on to other electron carriers until they are finally given to oxygen resulting in the production of water. WebDans les composés avec les éléments non-métalliques, l'hydrogène forme des liaisons covalentes, car l'ion H + a une forte tendance à s'associer avec les électrons. Dans les acides en solution aqueuse, il se forme des ions H 3 O + appelés ions « hydronium » ou « oxonium », association du proton et d'une molécule d'eau .
