The three-domain system adds a level of classification (the domains) "above" the kingdoms present in the previously used five- or six-kingdom systems.This classification system recognizes the fundamental divide between the two prokaryotic groups, insofar as Archaea appear to be more closely related to Eukaryotes than they are to other prokaryotes – bacteria-like organisms with no cell nucleus. 1 0. While water molecules can directly cross the membrane by passive diffusion, as mentioned above, channel proteins called aquaporins can enhance their transport, A substance called adenosine triphosphate (ATP) links most cellular exergonic. Are transport proteins that transport a substance from one side of the membrane to the other, Transport water or certain ions down either a concentration gradient, in the case of water, or an electric potential gradient in the case of certain ions, from an area of higher concentration to lower concentration. One reason for this is that the ether-containing linkages in theArchaea membranes is more stabile than the ester-containing linkages in the Bacteria and Eukarya and are better able to withstand higher temperatures and stronger acid concentrations.
