Which of the following pathways does NOT directly transfer
materials to lysosomes?
A. Exocytosis
B. Endocytosis
C. Autophagy
D.Macropinocytosis
Answer: is A.
Exocytosis does not directly transfer materials to lysosome.
Explanation : Exocytosis: It is the process by which substances of cell are brought out external to the cell via membrane containing organelles. And in case of exocytosis transfer of material take place outside of the lysosome. Transfer of lysosome mediated by membrane bound cell organelles, no directly transfer take place.
