10. Cell membranes are asymmetrical. Which of the following statements
are the most likely explanations for the membrane's asymmetrical nature?
(A) Since the cell membrane forms a border between one cell and another
in tightly packed tissues such as epithelium, the membrane must be
asymmetrical.
(B) Since cell membranes communicate signals from one organism to
another, the cell membranes must be asymmetrical.
(C) The two sides of a cell membrane face different environments and
carry out different functions.
(D) Proteins only function on the cytoplasmic side of the cell membrane,
which results in the membrane's asymmetrical nature.
(E) The two sides of membrane are structurally different. Different
phospholipids are found in each side of the membrane.
