batteries/fuel cells/electrolysis

[nels]

do we have to remember all the anode and cathode reactions in batteries, fuel cells and electrolysis(like the production of aluminium)?
or is it going to be provided in the question?

also, what about the electrolytes? do we have to remember what they are made of?

They should provide you with the electrolyte and at least one equation. Though it's useful to remember how they all work.
