Question:

The difference between pinocytosis and receptor-mediated endocytosis is that

B) pinocytosis increases the surface area of the plasma membrane whereas receptor-mediatedendocytosis decreases the plasma membrane surface area.

C) pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediatedendocytosis offers more selectivity.

D) pinocytosis requires cellular energy, but receptor-mediated endocytosis does not.

E) pinocytosis can concentratesubstances from the extracellular fluid, but receptor-mediatedendocytosis cannot.
