Correct answer: D. All of these
- A. Transport of molecules
- B. Mechanical support
- C. Conjugated molecules synthesis
- D. All of these
Explanation
The endoplasmic reticulum allows the transport of material in the cell and the synthesis of conjugated molecules (glycoproteins). The membranes of ER act as an ultrastructural skeletal framework in the cell and provide mechanical support.
