Is a cell membrane permeable or impermeable
WebOn the other hand, NaCl exists as hydrated Na+ and Cl- ions in solutions, that are charged and carry a large hydration shell. That is why it would require too much energy to dehydrate them and to bring them through the lipid bilayer. Ions can, however, pass cellular membranes through channels and transporters. WebCell membranes only allow some molecules through. This characteristic is why cell membranes are selectively permeable. They are not impermeable (not letting anything pass) nor are they freely permeable (letting everything can pass). This quality allows a cell to control what enters and exits it. This section of the course will further explore ...
