The Difference Between Pinocytosis and Receptor-Mediated Endocytosis is That

Question

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.

Accepted Answer

Pinocytosis is a nonselective process and brings a variety of molecules and fluids into the cell, whereas receptor-mediated endocytosis is a selective process that specifically targets molecules that bind to receptors on the surface of the cell. This allows for greater specificity and control over what substances are brought into the cell.
