Glycolipids and glycoproteins have structural role in the ______________ matrix of animal and bacterial cell?
Correct answer: A. Extracellular
- A. Extracellular
- B. Intracellular
- C. Both of these
- D. Glucose
Explanation
Glycolipids and glycoproteins contribute carbohydrate-containing structures to the extracellular matrix and cell surface, where they help with protection, adhesion and recognition. The likely mistake is intracellular, because these molecules are made inside cells, but the structural matrix being described lies outside the cells.

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.
