Select the INCORRECT statement about the plasma membrane:
a) cholesterol contributes to its fluidity by preventing phospholipid crystallization
b) proteins are not arrange in any particular order but can move within the membrane
c) carbohydrates are found only on the inner surface of the membrane
d) it consists mostly of phospholipids
e) membrane proteins serve a variety of functions
