Question
Chapter 7.6, Problem 1EQ
Summary Introduction
To predict: The way in which the movement of ATP synthase was observed by researchers.
Introduction: With the help of the enzyme, ATP synthase, ATP occurs in cells. It combines an inorganic phosphate molecule with ADP. An experiment was conducted to observe the ATP synthase molecule. The components of the molecule were observed to be too small to be visualized by a light microscope.

Focusing on the mechanism linking complex I and ATP synthase depicted in figure 3 in the article, compare that hypothetical mechanism to the classical presentation described in our textbook. What are the major differences between this mechanism and Peter Mitchel’s original chemiosmotic theory? What are the similarities.
The pH values of the different compartments are shown below:
matrix Intermembrane space Cytosol
pH 7.8 – 8.0 pH ~ 7.0pH 7.0 – 7.4
Proton flow through ATP synthase leads to the formation of ATP, a process defined as the binding-change mechanism that was initially proposed by Boyer.
Briefly explain Boyer’s binding change mechanism for the ATP synthase.
(e) Write 3 assumptions that could be made when using the type of support materials as suggested in (d).
