Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
a carbohydrate/complex that is involved in intercellular communication and cell recognition
A
Recognition marker
B
Transport protein
C
Phospholipid
D
Cholesterol channel
Explanation: 

Detailed explanation-1: -Glycolipids are membrane carbohydrates linked to lipids. These carbohydrate chains help in cell-to-cell recognition.

Detailed explanation-2: -Complex carbohydrates coat the surfaces of cells and have the potential to carry the information necessary for cell-cell recognition. Sugar-specific receptors (lectins) are also present on cells, and can interact with sugars on apposing cells.

Detailed explanation-3: -Proteins embedded within the phospholipid bilayer carry out the specific functions of the plasma membrane, including selective transport of molecules and cell-cell recognition.

Detailed explanation-4: -Membrane carbohydrates perform two main functions: participate in cell recognition and adhesion, either cell-cell signalling or cell-pathogen interactions, and they have a structural role as physical barrier.

Detailed explanation-5: -Complete answer: Branching side-chain glycolipids and glycoproteins on the outer surface of cell membranes are involved in cell-cell recognition.
