Multiple Choice
In the context of exocytosis, which process removes materials from a cell by transporting vesicle contents to the plasma membrane for release to the extracellular space?
A
Endocytosis
B
Osmosis
C
Exocytosis
D
Phagocytosis
Verified step by step guidance1
Understand the definition of exocytosis: it is the process by which cells transport materials in vesicles to the plasma membrane, where the vesicle fuses with the membrane and releases its contents outside the cell.
Recognize that endocytosis is the opposite process, where the cell takes in materials by engulfing them in vesicles formed from the plasma membrane.
Recall that osmosis refers to the passive movement of water across a semipermeable membrane, not involving vesicle transport.
Identify phagocytosis as a specific type of endocytosis where large particles or cells are engulfed by the cell.
Conclude that the process described—removing materials from the cell by vesicle fusion with the plasma membrane—is exocytosis.
