An animal cell lacking oligosaccharides on the external surface of its plasma membrane would likely be impaired in which function?
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules

Question

Quizplus · Accepted Answer

Oligosaccharides on the external surface of the plasma membrane function in cell-cell recognition by allowing cells to identify and communicate with each other. Without these oligosaccharides, the cell would be impaired in its ability to recognize and interact with other cells.
