Question

The major site of cell membrane synthesis is the
A)nucleus.
B)plasma membrane.
C)lysosome.
D)endoplasmic reticulum.

Accepted Answer

The endoplasmic reticulum is the major site of cell membrane synthesis in eukaryotic cells. The ER is responsible for the synthesis, folding, and modification of membrane proteins and lipids, which are then transported to other parts of the cell. The plasma membrane is not a site for membrane synthesis but rather a structure composed of these synthesized lipids and proteins. The nucleus contains genetic information and is not involved in membrane synthesis, and lysosomes are organelles responsible for breaking down cellular waste and foreign substances.
