    cell produce protein means RER in which protein formed and modify in golgi mean gycosylated and all,so when cell produce much protein ,its packed in a large vesicle and send to lysosome for diffirent kind of function enzme to produce.enzme is protein ,right.so lysosome has dnaase,protease like.enzme protein.fine.
