Final answer:

Oxidation occurs at the anode, and reduction occurs at the cathode in both galvanic and electrolytic cells.


Explanation:

In both galvanic and electrolytic cells, oxidation occurs at the anode and reduction occurs at the cathode.

For example, in a voltaic cell, like a battery, the spontaneous redox reaction produces electricity as electrons flow from anode to cathode. On the other hand, in an electrolytic cell, nonspontaneous redox reactions are driven by an external power supply.

Remember, the flow of electrons is from anode to cathode in both types of cells, with oxidation happening at the anode and reduction happening at the cathode.
