That's far too much for **A** question. So I'm not going to bother with at least half of it.
Fo/ F1: Together, they form an ATP synthase
structure: Fo is in the membrane and F1 is a "knob" that sits just 'above' the membrane. The Fo has a number (6 to 10) of c subunits which form a ring that spins as protons flow through the Fo. The Fo also has an a and a b subunit, which are stationary. The F1 part has 3 alpha and 3 beta subunits which are immobile. Geez, this would take a long to write, so I'll just add one more part. There is a gamma subunit that acts as a rotating shaft: as the c subunits of Fo spin they rotate the gamma subunit, which spins within the alpha3beta3 region of the F1. The gamma subunit is asymmetric, so its spininng causes the alpha and beta subunits of F1 to cycle through 3 different conformational states, each with a different affinity for ADP, Pi, or ATP.
where: In mitochondria, in the inner mitochondrial membrane. In chloroplasts, in the thylakoid membrane. In prokaryotes, in the plasma mebrane.
function: Combine ADP and Pi into ATP; this is powered by the flow of protons through the Fo subunit.
substrates: ADP, Pi, and H+
products: ATP and H2O
