what is the function of carbohydrates in the cell membrane?
protection against pathogens.
energy storage.
dna replication.
facilitating cell division.
cell recognition and adhesion.

Explanation:

Carbohydrates in the cell - membrane are mainly involved in cell - recognition and adhesion. They form glycoproteins and glycolipids which help cells recognize each other and adhere to other cells or the extracellular matrix. Protection against pathogens is more related to immune cells and antibodies. Energy storage is mainly the role of fats and some polysaccharides in the cytoplasm, not in the cell - membrane. DNA replication is related to nucleic acids and enzymes in the nucleus or cytoplasm. Facilitating cell division involves proteins and regulatory molecules.

Answer:

Cell recognition and adhesion.
