Oxidation occurs at the anode; whereas deposit of metallic copper occurs in the cathodic reaction.
Explanation:
At the cathode, reduction occurs:
If it's a carbon electrode, you will see it develop a salmon-pink coloured coating of copper metal.
On the other hand, the anodic reaction features oxidation. What could be oxidized? Well, really the only candidates are the oxygen atoms of water, which is oxidized from
The sulfate anion,
