Which of the following bacteria have more lipids in their cell wall?
Correct answer: B. Gram-negative bacteria have more lipids in their cell wall
- A. Gram-positive bacteria have more lipids in their cell wall
- B. Gram-negative bacteria have more lipids in their cell wall
- C. Lipids are absent in cell wall of both gram positive and negative bacteria
- D. Both have equal amount of lipids
Explanation
Gram-negative bacteria have a more complex cell wall structure compared to gram-positive bacteria. The outer membrane of gram-negative bacteria contains lipopolysaccharides (LPS), which are lipid-rich molecules. This presence of LPS contributes to a higher lipid content in the cell wall of gram-negative bacteria. In contrast, gram-positive bacteria have a simpler cell wall structure with a thicker layer of peptidoglycan and fewer lipids.
