24. What is the difference between pinocytosis and receptor-mediated endocytosis (A) pinocytosis brings only water molecules 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 can concentrate substances from the extracellular fluid, but receptor- mediated endocytosis cannot
