Question

Lipid molecules in the cell are sythesized by

Options

• smooth endoplasmic reticulum

• rough endoplasmic reticulum

• golgi apparatus

• plastids

Answer 1

smooth endoplasmic reticulum

Explanation - 

Lipid molecules in the cell are synthesised by the smooth endoplasmic reticulum present in the cell.

 The proteins and lipids, essential for building the cell membrane, are respectively manufactured by rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The lipid molecules for the cell membrane are formed and inserted into the membrane of smooth ER by smooth ER itself. The protein molecules of the cell membrane are mostly synthesized and inserted into the membrane at the level of rough ER.
