Lipids and proteins, which constitute the cell membrane, are synthesized within the cell. Specifically, lipids are primarily synthesized in the endoplasmic reticulum (ER), a network of membranes within the cell. The ER plays a crucial role in lipid synthesis, including the production of phospholipids, which are the main components of the cell membrane.
On the other hand, proteins that make up the cell membrane are synthesized by ribosomes, which can be found either bound to the rough endoplasmic reticulum (RER) or free in the cytoplasm. The RER-bound ribosomes are responsible for the synthesis of proteins that are destined to be embedded or associated with the cell membrane.
After synthesis, both lipids and proteins undergo further processing and modification within the cell before being transported to the cell membrane or other cellular compartments, where they contribute to the structure and function of the cell membrane.
Answers & Comments
Verified answer
Answer:
Cell membrane synthesis:
The cell membrane is made up of bilayer of phospholipid (a kind of lipid) and proteins embedded in it.
The synthesis of proteins and lipids takes place in the endoplasmic reticulum.
It is of two types- smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER).
The lipid synthesis occurs in the smooth endoplasmic reticulum (SER).
Rough endoplasmic reticulum (RER) has ribosomes attached to its membrane.
Ribosomes are the factory of all protein being synthesised in the cell.
Therefore, membrane proteins are also synthesised by rough endoplasmic reticulum (RER).
Final answer:
The lipids and proteins constituting the cell membrane gets synthesised in smooth
endoplasmic reticulum (SER)
and
rough endoplasmic reticulum (RER)
, respectively.
