Question

Quizplus · Accepted Answer

Endocytosis is the process by which large molecules, such as proteins or polysaccharides, are transported into the cell. The plasma membrane forms a pocket around the molecule, pinches off, and forms a vesicle that carries the molecule into the cytoplasm of the cell. Option A is incorrect as the plasma membrane does not turn itself inside out during endocytosis. Option B is incorrect as the digestion of large molecules happens after they are brought into the cell. Option D is incorrect as endocytosis is the transport of molecules into the cell, not out of the cell.
