Questions & Answers

The cell organelle which is actively involved in membrane biogenesis is,
A) Endoplasmic reticulum
B) Golgi apparatus
C) Lysosomes
D) Vacuoles

Answer Verified Verified
Hint: The process of formation of the cell membrane of the cell is called membrane biogenesis or membrane synthesis. Membrane biogenesis is a highly dynamic process. In membrane biogenesis firstly proteins and lipids are produced, that they get assembled to form the semi-permeable membrane.

Complete Answer:
1) There are two types of endoplasmic reticulum found in cells, rough endoplasmic reticulum, and smooth endoplasmic reticulum. The presence of ribosomes makes the surface rough. Ribosomes produce proteins, that’s why they are called protein-factory of the cells. The smooth endoplasmic reticulum is involved in lipid synthesis.
2) The Golgi apparatus also known as the Golgi body. Golgi apparatus is involved in transportation, modification, and packaging proteins and lipids that are synthesized in the endoplasmic reticulum into vesicles.
3) A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They remove waste material from the cells and also kill the bacteria and viruses.
4) Vacuoles are empty cell organelle that performs functions such as storage, ingestion, digestion, excretion.

So, ‘endoplasmic reticulum’ is the correct answer.

Note: The structure of the cell membrane contains proteins, phospholipids, glycolipids, and glycoproteins. The phospholipids are the basic component of the cell membrane. The primary function of the cell membrane is to protect the cell from surrounding and also controls the transportation of the chemicals, ions, molecules from and to the cell.
