Electron transport in proteins is crazy complex and actually amounts to molecular circuits where energy is guided to different spots inside proteins complexes in a unidirectional fashion. This guy is the grand daddy of the field (https://www.youtube.com/watch?v=ge7m9-PEiB8).
I can't find an accessible video on the topic, but you want to look up photosystem II repair. You need to search up D1 replacement in photosystem II.
To get a flavour of the nanomachine aspect of it all, check out this video on electron transport across membranes (https://www.youtube.com/watch?v=LQmTKxI4Wn4).
