MCQ
Lipids and proteins constituting the cell membrane are synthesized at:
- AEndoplasmic reticulum
- BMitochondria
- CGolgi apparatus
- DLysosome
Explanation:
The endoplasmic reticulum bearing ribosomes on their surface called as rough endoplasmic reticlum (RER) which are actively involved in protein synthesis. The smooth endoplasmic reticulum (SER) is the major site for synthesis of lipid. In animal cells, steroidal hormones synthesized in SER. Lipids are synthesized in smooth endoplasmic reticulum (SER) and the proteins are synthesized in rough endoplasmic reticulum (RER). The lipids and proteins together forms plasma membrane by the process of membrane biogenesis.
