Q. The main organelle involved in modification and routing of newly synthesized proteins to their destinations is :
A) mitochondria
B) endoplasmic reticulum
C) lysosome
D) chloroplast
Explanation
[Solution from source] Proteins made on ribosomes attached to the rough endoplasmic reticulum enter its lumen, where they are folded, glycosylated and packed into vesicles for transport onward (via the Golgi) to their destinations. Mitochondria and chloroplasts make ATP and food, and lysosomes digest material; none of them sort and route new proteins. Answer (2).
