Chapter 18, Problem 6P

Interpretation Introduction

Interpretation : 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.
