Question

Given below are two statements: 
• [Statement (I):] The lipids found in the inner (cell) membrane of bacteria are phospholipids. 
• [Statement (II):] The lipids in the outer membrane of Gram negative bacteria contain both phospholipids and lipopolysaccharides. 
In light of the above statements, choose the most appropriate answer from the options given below. 
 

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

The lipopolysaccharide (LPS) in the outer leaflet of Gram-negative bacteria acts as a barrier against toxic molecules (including many antibiotics).
It is also the endotoxin responsible for triggering severe immune responses (toxic shock) in animals.
