The difference between pinocytosis and receptor-mediated endocytosis is that
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 requires cellular energy, but receptor-mediated endocytosis does not.
E) pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot.

Question

Quizplus · Accepted Answer

Pinocytosis is a type of endocytosis that is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis is more selective because it involves the use of specific receptors to recognize and bind to target molecules before they are brought into the cell. Option A, B, D, and E are incorrect because they do not accurately distinguish between pinocytosis and receptor-mediated endocytosis.
