Why two types of single - celled organism that form the deepest branch on the tree of life — bacteria and archaea — have completely
different cell membranes
The study suggests that the bacteria and archaea developed completely
different cell membrane structures and proton pumps, whilst keeping the same machinery for powering growth.

So it makes you think that, well, maybe that could have been one contributing factor to why we actually use genetic materials that incorporate ribose, because early
cells that relied on an external source of ribose would have had easier access to that material compared to competing the
cells that we're looking for, a
different sugar that had a harder time getting across the
membrane.

cell membrane are able to interact with
different substances, and understand how differences in metal and mineral interactions can occur on the surface of a
cell.
There are also differences in the affinity of
different transporters for specific drugs: for example, the high - affinity transporters OCT1 and / or OCTN2 are functional at the basolateral
membrane of rat Sertoli
cells, whereas the low - affinity transporters OCT3 and / or OCTN1 are functional at the apical
membrane (43).

different forms of which are involved in
membrane fusion in all
cells, and in
