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