The upcoming discussion will update you about the differences between respiration and fermentation.
Respiration:
1. It may occur both in the presence and absence of oxygen.
2. Occurs only in living cells.
3. Sugar is oxidized and CO2 and H2O are formed as end products.
4. Complete oxidation of substrates occurs, hence produces large amount of energy.
5. It can occur in any living cell.
Fermentation:
1. It does not require oxygen.
2. It does not occur within the living cells. It requires only enzymes and substrate.
3. Different substrates oxidize to form alcohol or organic acids.
4. Incomplete oxidation of substrate occurs and, hence less energy is produced.
5. It occurs mainly with the help of yeast or bacterial cells.
