“Exclusion zones” (EZ) were observed as a lining of various depths on a hydrophilic surface in water-containing objects, including, most probably, hydrophilic membranes in biological cells. Indications for the presence of EZs inside living biological cells are scarce. A surprising property is that this kind of water moiety excludes any solutes, from emulsified objects down to molecules. One of the possible implications could be that, inside the cell, substrates for membrane-bound enzymes could have no access to their enzymes due to exclusion by this water moiety covering the hydrophilic membranes. A possible solution for this problem, created during evolution, is presented and discussed.
