The influence of c-subunit stoichiometry on the efficiency of ATP synthesis
The number of c-subunits in F1F0-type ATP synthases shows some variation from organism to organism. For example, the yeast ATP synthase contains 10 c-subunits, the spinach CF1CF0-ATP synthase has 14, and the cyanobacterium Spirulina platensis enzyme apparently has 15.
a. What is the consequence of c-subunit stoichiometry for the H+/ATP ratio
b. What is the relationship between c-subunit stoichiometry and the magnitude of p (the protonmotive force)
