The phosphorylation of ADP necessitates four protons. In this procedure, account for the role of each proton.
Proton motive force refers to
A) the movement of protons across a membrane due to a proton gradient.
B) the flow of electrons through an electron transport chain.
C) the action of ATPase enzyme.
D) oxidative phosphorylation.
E) the oxidation of NADH2 and FADH2.
In terms of an electrochemical gradient being produced, compare and contrast any three (3) systems whereby a proton motive force is generated. Why is producing and maintaining a consistent proton motive force important? What potential problems could arise if the proton motive force becomes too high or too low, and how are these remedied? Discuss why in some instances a sodium motive force may be more appropriate than a proton motive force.
