The comparison between fermentation and respiration in terms of electron donors and electron acceptors needs to be explained. Concept Introduction : An electron transport chain (ETC) is the series of redox reactions that involve the transfer of electrons from electron donors to electron acceptors. This transfer of electrons is coupled with the proton transfer (H + ) across the membrane. This then creates the electrochemical gradient resulting in the formation of ATP.

Concept Introduction : An electron transport chain (ETC) is the series of redox reactions that involve the transfer of electrons from electron donors to electron acceptors. This transfer of electrons is coupled with the proton transfer (H⁺) across the membrane. This then creates the electrochemical gradient resulting in the formation of ATP.

Expert Solution & Answer

Answer to Problem 1P

In fermentation both, electron donors and acceptors are organic compounds. But in respiration, electron acceptor can be an inorganic molecule.

Explanation of Solution

Fermentation is the process of conversion of pyruvate into lactic acid or alcohol. This takes place in the absence of oxygen only. During the process of fermentation, pyruvate is the electron acceptor and NADH is the electron donor. This means, in fermentation, the organic compound acts as both electron donor and electron acceptor.

During the process of respiration, oxygen is present. In this process, NADH acts as the electron donor and oxygen is the final electron acceptor. So, in this process, the electron donor is an organic molecule, while an electron acceptor is an inorganic molecule.

Conclusion

In fermentation both, electron donors and acceptors are organic compounds. But in respiration, electron acceptor can be an inorganic molecule.
