By studying the ability of a shell-less egg to absorb various solutions, students can see how membranes can regulate a cell’s interaction with its environment. California Science Content Standards: • 1.
WebThe chemical structure of the cell membrane makes it remarkably flexible, the ideal boundary for rapidly growing and dividing cells. Yet the membrane is also a formidable barrier, allowing some dissolved substances, or solutes, to pass while blocking others. Lipid-soluble molecules and some small molecules can permeate the membrane, but the lipid … Webdisplayed a steep drop-off in membrane permeability at molecular weights above 1000 Da and it appears likely that this cutoff constitutes an upper size limit also for more druglike …
