The difference between pinocytosis and receptor-mediated endocytosis is that
A)
pinocytosis brings only water into the cell, but receptor-mediated endocytosis brings in other molecules as well.
B)
pinocytosis increases the surface area of the plasma membrane whereas receptor-mediated endocytosis decreases the plasma membrane surface area.
C)
pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.
D)
pinocytosis requires cellular energy, but receptor-mediated endocytosis does not.
E)
pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot.
