Question
Biology Question on Cell: the unit of life
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
Answer
endoplasmic reticulum
Explanation
Solution
The endoplasmic reticulum (ER) plays a crucial role in protein synthesis, modification, and transport within the cell. It is involved in folding, glycosylation, and other post-translational modifications of proteins, and it helps direct proteins to their appropriate destinations within the cell or for secretion outside the cell.
So, the correct option is (B): endoplasmic reticulum
