They both are heterotrophs. Both are multicellular eukaryotes. Both reproduce sexually. Both have mitotic and meiotic cell division. Hope this helped=)
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.
