To be alive, most cells must maintain a relatively constant internal enviornment. To do
this, they must be able to control the movement of materials into and out of the cell.
What characteristics of the cell membrane determine what get into the cell and what doesn't?
That is, what determines the permeability of a cell or organelle membrane? To answer these
questions, first consider the answer to the following questions:
f a cell membran were
composed of only a
phospholipid bilayer,
what properties would
it have?
Wha different roles or
functions do membrans
proteins serve?
Why are some cell types
more permeable to
a substance (for example,
sodium ions) than others?
Please answer in great detail please, thank you.
