Which transport process always involves the movement of materials from inside the cell to outside the cell?
a. phagocytosis
b. endocytosis
c. exocytosis
d. diffusion
c. exocytosis (I have to use 20 characters to respond and "answer it well". Exo means out/outside and exocytosis is an active transport system where a cell uses energy to transport material, like protein or waste, from inside a cell to the outside.)
