Which of the statement is not true for compounds like glycoproteins and glycolipids?
Correct answer: D. Both are produced and seceted by the endoplasmic reticulum
- A. They are conjugated molecules of carbohydrates
- B. Both have a role in extracellular matrix of animal and bacterial cell wall
- C. They are components of biological membranes
- D. Both are produced and seceted by the endoplasmic reticulum
Explanation
Proteins and lipids themselves are formed in rough and smooth endoplasmic reticulum respectively, but their conjugation with carbohydrates i.e. formation of glycoproteins and glycolipids occurs in Golgi bodies.

About Conjugated Molecules
Conjugated molecules contain a non-protein component attached to a protein portion, giving the molecule properties that a simple protein lacks. The content includes glycoproteins, lipoproteins, phosphoproteins, nucleoproteins, chromoproteins and metalloproteins, with attention to their prosthetic groups and roles in transport, protection, catalysis and cellular structure.
