  • Pinocytosis
  • Phagocytosis
  • Caveolae
  • Receptor-mediated endocytosis (correct)
  • What is the fate of vesicles containing substances internalized by endocytosis?

  • They are released from the cell through exocytosis
  • They are stored in the Golgi apparatus
  • They fuse with the mitochondria
  • They fuse with the lysosome (correct)
