Question

The amount of murein in gram-positive bacteria is:

• A. 50-60
• B. 20-40
• C. 10-20
• D. 70-80

Hint:

Gram-positive bacteria have a thick peptidoglycan layer, which is important for structural integrity and makes them more susceptible to antibiotics that target the cell wall.

Answer 1

The Correct Option is A

In gram-positive bacteria, the cell wall is primarily composed of murein, also known as peptidoglycan. This is a crucial component, providing structural integrity and protection to the bacterial cell. Gram-positive bacteria have a thick peptidoglycan layer compared to gram-negative bacteria.

The amount of murein in gram-positive bacteria is typically between 50-60% of the cell wall weight. This high percentage is due to the robust nature of their cell wall, which is essential for maintaining shape and withstanding internal turgor pressure.

The correct answer is: 50-60.
