I think the answer is electrons. The relationship between a cathode and an anode involves electrons. Hope this helped! :)
Answer is: electrons.
For example, balanced equation for the overall reaction:
C₂H₅OH + 3O₂ → 3H₂O + 2CO₂.
Galvanic cell has anode and cathode and half reactions are:
Anode reaction: C₂H₅OH + 3H₂O → 12H⁺ + 12e⁻ + 2CO₂; oxidation.
Cathode reaction: 3O₂ + 12H⁺ + 12e⁻ → 6H₂O; reduction.
Electrons are transported from anode to cathode.
