D)exocytosis.

Question

Quizplus · Accepted Answer

Receptor-mediated endocytosis is the process where molecules bind to specific receptor sites on the cell membrane and are then enclosed in vesicles that are transported into the cell. This is different from phagocytosis, which is the engulfment of large particles or cells, and pinocytosis, which is the non-specific uptake of fluid and small particles. Exocytosis is the opposite process where vesicles fuse with the cell membrane and release their contents outside the cell.
