1.alpha subunit has the binding sites of ADP,while beta subunit have catalytic sites for synthesis of ATP
2.subunit c is called rotator ring. For the ATP synthesis c subunit is rotated in a such way that alpha and subunit undergo confirmational change that enables binding of ADP and leads to ATP synthesis. a subunit help to connect c subunit with b subunit

The rotor portion of the ATP synthase is composed of 10-14 subunits called "c subunits." As protons bind the rotor, on the intermembrane space side of the rotor, the rotor turns one subunit worth of distance. If the rotor of ATP synthase is composed of 10 c subunits, how many protons would be necessary to produce 6 ATP molecules?
Imagine a new organism with 4 c subunits in the Fo portion of ATP synthase. (a)...
Imagine a new organism with 4 c subunits in the Fo portion of ATP synthase. (a) Assuming the rest of metabolism and the ETC are the same as in known organisms, how many ATP are produced per NADH oxidized? (b) Describe, in qualitative terms, the relationship between the amount of ATP synthesized per NADH oxidized and the number of c subunits in ATP synthase (i.e. if there are fewer subunits, what does that do to the number of ATP molecules...

A representation of the structure of the mitochondrial ATP synthase is presented in Figure 2 of this document. Notably, the chloroplast version of the spinach ATP synthase is remarkably similar to the mitochondrial version of the ATP synthase, with one notable exception. In the Fo portion of the chloroplast ATP synthase there are 14 "c" subunits. Discuss this noteworthy structural difference in the ATP synthases relative to the values you calculated in parts D and E of this problem. F)...

The Fo stalk component of ATP synthase is named such because it is rendered useless by the antibiotic oligomycin. Which of the following would occur in the presence of oligomycin? A. The catalytic Loose site of the FoF1 ATP Synthase would be unable to bind ADP and Pi. B. The influx of protons and the rotation of the c subunits would slow and possibly сease. C. The y subunit would dissociate from the a and B subunits. D. All of...
