Biology Question on Eukaryotic Cells
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.
Answer
endoplasmic reticulum.
Explanation
Solution
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. Here, they are further processed and packaged into secretory vesicles for export
