Instead, it seems more likely that this organism biomineralizes and arranges endogenous magnetite crystals in a highly controlled fashion within the cell where intracellular structural elements play a significant role in magnetosome, as has been shown for magnetotactic prokaryotes.

I grasped the cold slimy rung. My feet slithered and scrunched on stranded things. Next rung...the next and next...endless horrible rungs, hissing and smells belching from under the wharf.

In particular, the emerging consensus that the complexes I-III-IV occur mostly as supercomplexes further complicates attributing shifts in the CoQ redox state to a specific location in the mitochondrial ETC as electron transfer in these supercomplexes appears to occur via tunnelling or microdiffusion of CoQ/CoQH 2 rather than via a mobile CoQ pool in mitochondrial membranes [72 ].
