The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.

When copper is heated to temperatures of around 870-980 degrees Celsius, it will begin to oxidize—meaning that it will react with oxygen from the air to form copper oxide. The oxidation process creates two distinct layers on the surface of the copper—a thin outer layer of black copper oxide and an inner layer of red-brown cupric oxide.

Redox reactions are comprised of two parts, a reduced half and an oxidized half, that always occur together. The reduced half gains electrons and the oxidation number decreases, while the oxidized half loses electrons and the oxidation number increases.Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD +, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy. Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA.Reduction and oxidation happen at the same time, so the reactions are called redox reactions close redox reaction When reduction and oxidation take place at the same time..
