A-level Biology AQA

Hey guys, I just wanted to ask what are ALL the reactions that takes place in the cell surface membrane for the whole aqa syllabus. Cos I'm sure this was such a small topic in cells before and it's just brought up everytime (not surprised!) but I just need help cos I'm working on a C.

I know chemiosmosis do, but I just can't remember the rest on top of my head. Thanks in advance
