Chapter 7.4, Problem 2SB
Summary Introduction
To review:
The way proton pumps of the complexes I, III, and IV relate to the synthesis of ATP.
Introduction:
The mitochondrial electron transfer system comprises a series of electron carriers which alternately pick up and produce electrons, and finally transfer them to their acceptor, the final electron acceptor is oxygen. This system comprises three primary protein complexes that provide the electron carriers. These protein complexes are numbered as I, III, and IV and are known as the integral membrane proteins.
