In the fluid mosaic model of a typical plasma

membrane, what accounts for the fluidity?



a. the proteins, being large, cause the
membrane to jiggle around.
b. the phospholipids collectively form a jellylike
substance similar to the cytoplasm.
c. the phospholipids are not bonded to each
other and thus are more free to move
around.
d. water molecules infiltrate the bilayer
causing it to become more watery and thus
more fluid.
e. the phospholipids in a typical plasma membrane form covalent bonds which are
elastic and allow the membrane to ‘stretch’.
