Consider the remarkable structure of the F1Fo ATP synthase shown in the following schematic drawing. Answer the following question(s) based on the structure.

-In the schematic drawing of the structure of ATP synthase shown above, indicate whether each of the numbered components of the machine (from 1 to 5, respectively) is rotary (R) or stationary (S). Your answer would be a five-letter string composed of letters R and S only, e.g. RRSRS.
