cell membrane structure Flashcards
what is significant about the permeability of the cytoplasmic membrane?
highly selective permeability allowing concentration of specified metabolites while excreting waste products
what is the cytoplasmic membrane?
vital, thin structure that surrounds the cell, protecting the cytoplasm from the environment
the basic composition of the membrane structure is comprised of
a phospholipid bilayer
phospholipid bilayer has
a hydrophobic and a hydrophilic component
the composition of the membrane can exist as many different chemical forms because
it has a glycerol backbone attaching various groups arranged to it
what part of the phospholipid bilayer phases inward and outward?
the fatty acid (glycerol) faces inward to form the hydrophobic region
the rest of the phospholipid portions face outward making the external region of the cell hydrophilic
