During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
NAD+ gets oxidized by accepting electrons (and protons) during redox reactions. It is reduced to NADH when it accepts these electrons.
In the given reaction, the hydrogen sulfide (H2S) is the element that gets oxidized. The sulfur in H2S changes from a -2 oxidation state to 0 in sulfur dioxide (SO2), indicating oxidation.

Ni2+
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
