proteins & lipids - Answer-cell membranes contain which major chemical components?
proteins & lipids - Answer-what acts like molecular glue for integrity of the membrane
structure?
lipids - Answer-what are molecules that are polar/amphipathic?
polar/amphipathic - Answer-part hydrophobic and part hydrophilic
Mg2+ - Answer-magnesium
NaCl - Answer-sodium chloride
, hydrophobic - Answer-uncharged/water hating
hydrophilic - Answer-charged/water loving
lipid bilayer - Answer-serves as a barrier to the diffusion of water and hydrophilic
substances, while allowing lipid-soluble molecules like oxygen and carbon dioxide to
diffuse readily.
