Vedclass · Answer

(B) Based on the structure of the plasma membrane:$A$ points to a carbohydrate chain attached to a protein,which is a Glycoprotein,responsible for cell-to-cell recognition.$B$ points to an integral protein forming a channel,which is a Tunnel protein,facilitating the transport of polar molecules.$C$ represents the Lipid Bilayer,which forms the structural framework of the membrane.$D$ points to Cholesterol molecules embedded within the bilayer,which provide stability and regulate membrane fluidity.Therefore,the correct matching is $A \rightarrow$ Glycoprotein,$B \rightarrow$ Tunnel protein,$C \rightarrow$ Lipid Bilayer,$D \rightarrow$ Cholesterol.

The given diagram shows a sectional view of the plasma membrane. Identify the labelled parts and their functions.
