In the process of respiration, glucose is oxidized completely. In fermentation, O ₂ is absent and glucose is broken down to ethanol and CO₂. Ethanol is oxidized to CO ₂ and H₂O.

(a) Balance the following equations for these processes:

  Respiration:    C₆H₁₂O₆(s) + O₂(g) ⟶ CO₂(g) + H₂O(l)
  Fermentation:   C₆H₁₂O₆(s) ⟶ C₂H₅OH(l) + CO₂(g)
  Ethanol oxidation:   C ₂H₅OH(l) + O₂(g) ⟶ CO₂(g) + H₂O(l)
