Question

Because nadh generated in the cytosol cannot enter the mitochondrion, electrons and protons from nadh are transferred in by __________.

Answer 1

I think the correct term to fill in the blanks would be glycerol phosphate electron shuttle. This shuttle is responsible of transporting agents that are reducing into the inner membrane of the mitochondria. Since NADH cannot enter, it is reduced so that the electrons could go in to the transport chain.
