Pick up the component which is comparatively in greater amount in Gram Negative cell wall:
Correct answer: A. Lipids
- A. Lipids
- B. Peptidoglycan
- C. Teichoic acid
- D. Lipoteichoic acid
Explanation
The correct answer is Lipids. Gram-negative bacteria have a unique cell wall structure characterized by an outer membrane rich in lipids, including lipopolysaccharides (LPS), phospholipids, and lipoproteins. This lipid-rich outer membrane provides a protective barrier and plays a significant role in the bacteria's interaction with its environment. In contrast, the peptidoglycan layer in Gram-negative bacteria is much thinner than in Gram-positive bacteria, and teichoic and lipoteichoic acids are absent as they are specific to Gram-positive bacteria.
