Which of the following conjugate molecules are present as surfactants in respiratory distress syndrome?
Correct answer: D. Lipoproteins
- A. Glycolipids
- B. Glycoproteins
- C. Lipopolysaccharides
- D. Lipoproteins
Explanation
They act as surfactant during respiratory distress syndrome when surfactant production is insufficient or absent, which causes alveolar collapse, decreased lung compliance, and impaired oxygenation. This often occurs in premature infants whose lungs are underdeveloped.

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.
