Question

Correct sequence of layer of bacterial cell envelope from outward to inward is

• A. Cell wall $\to$ Glycocalyx $\to$Cell membrane
• B. Cell membrane $\to$ Glycocalyx $\to$ Cell wall
• C. Glycocalyx $\to$ Cell wall $\to$ Cell membrane
• D. Glycocalyx $\to$ Cell membrane $\to$ Cell wall

Answer 1

Answer: (C)

Glycocalyx $\to$ Cell wall $\to$ Cell membrane

Glycocalyx is the outermost layer of the cell envelope. Cell wall lies between plasma membrane and glycocalyx.

So, the correct answer is 'Glycocalyx → Cell wall → Cell membrane'.
