The main organelle involved in modification and outing of newly synthesized proteins to their destinations is (a) chloroplast (b) mitochondria (c) lysosome (d) endoplasmic reticulum.
Option D The proteins formed on ribosomes pass into the ER lumen where they are modified. Then the modified proteins move on into the transitional area, where the ER buds off membranous sacs, the transport vesicles, carrying the proteins to the Golgi apparatus.
