A primary function of carbohydrates attached to the glycoproteins and glycolipids of animal cell membranes is to ________.
A) facilitate diffusion of molecules down their concentration gradients
B) actively transport molecules against their concentration gradients
C) maintain the integrity of a fluid mosaic membrane
D) maintain membrane fluidity at low temperatures
E) mediate cell-cell recognition

Question

Quizplus · Accepted Answer

Carbohydrates attached to glycoproteins and glycolipids serve as unique identification tags on the surface of cell membranes, allowing cells to recognize and communicate with one another. This process is known as cell-cell recognition and is critical for many aspects of cellular function, including immune system response, development, and the maintenance of tissue structure.
