In cell biology, is exocytosis considered active transport or passive transport?
A
Passive transport, because exocytosis is simply diffusion through membrane pores.
B
Neither; exocytosis is a form of osmosis driven only by water potential differences.
C
Active transport, because vesicle fusion with the plasma membrane requires energy (e.g., ATP) and cytoskeletal machinery.
D
Passive transport, because substances move down their concentration gradient through the lipid bilayer without energy input.
