Question

Organelle involved in modification and routing of newly synthesised proteins to their destination is

• A. Chloroplast
• B. Lysosome
• C. Mitochondrion
• D. Endoplasmic reticulum

Answer 1

The correct option is D Endoplasmic reticulum

• The endoplasmic reticulum (smooth and rough) is an interconnected network of flattened, membrane-enclosed sacs or tube-like structure which are evenly distributed throughout the cytoplasm.
  
• The factory of a cell is known as rough endoplasmic reticulum (studded with ribosomes).
  
• The RER along with the ribosomes manufacture proteins and transport them to other parts of the cell (protein synthesis)
• So, the correct answer is 'Endoplasmic reticulum'.
