In this reaction, carbon is oxidised because it gains oxygen. At the same time, copper oxide is reduced because oxygen is removed from it.

Redox enzymes are proteins that catalyze oxidation-reduction reactions, which involve the transfer of electrons between molecules. Redox enzymes are ...

The spontaneity of redox reactions is demonstrated using copper ... When solid copper is placed in Ag+ solution, the solution becomes faintly blue as copper metal is oxidized to Cu2+. White slivers of ...
