Which of the following are possible functions of glycoproteins in the plasma membrane?
A
Energy production
B
Cell recognition and signaling
C
Protein synthesis
D
DNA replication
Verified step by step guidance1
Understand the structure of glycoproteins: Glycoproteins are molecules that consist of a protein and a carbohydrate (sugar) chain. They are embedded in the plasma membrane of cells.
Identify the role of glycoproteins in the plasma membrane: Glycoproteins play a crucial role in cell-cell interactions, serving as recognition sites for other cells and molecules.
Explore the function of cell recognition: Glycoproteins are involved in the immune response by helping the body recognize its own cells versus foreign cells, which is essential for immune function.
Examine the role in cell signaling: Glycoproteins can act as receptors for signaling molecules, allowing cells to communicate with each other and respond to changes in their environment.
Differentiate from unrelated functions: Energy production, protein synthesis, and DNA replication are not functions of glycoproteins in the plasma membrane. These processes occur in different cellular contexts and involve other cellular components.
