Multiple Choice

Which of the following statements concerning carbohydrates associated with the plasma membrane is correct?

Carbohydrates are found associated with the membranes of prokaryotic cells only.

The carbohydrate composition of most eukaryotic plasma membranes is quite similar.

Carbohydrates on the plasma membrane are typically long, complex chains of several dozen monosaccharides.

Carbohydrates associated with the plasma membrane are located on both surfaces of the membrane.

Membrane carbohydrates function primarily in cell-cell recognition.

Verified step by step guidance

Understand the role of carbohydrates in the plasma membrane: Carbohydrates are crucial for cell-cell recognition, which is essential for the immune response and tissue formation.

Identify the location of carbohydrates in the plasma membrane: In eukaryotic cells, carbohydrates are typically found on the extracellular surface of the plasma membrane, not on both surfaces.

Consider the structure of membrane carbohydrates: They are often short chains of monosaccharides, forming glycoproteins and glycolipids, rather than long, complex chains.

Differentiate between prokaryotic and eukaryotic cells: Carbohydrates are associated with the plasma membranes of eukaryotic cells, not exclusively prokaryotic cells.

Evaluate the diversity of carbohydrate composition: The carbohydrate composition of eukaryotic plasma membranes can vary significantly between different cell types and organisms, contrary to being quite similar.
