Which of the following CAMs work by binding to sugars on the plasma membrane in order to promote cell-cell adhesion?
A
Lectins
B
Selectins
C
Mectins
D
Cadherins
Verified step by step guidance1
Understand the role of Cell Adhesion Molecules (CAMs) in cell biology, which are proteins located on the cell surface involved in the binding with other cells or with the extracellular matrix.
Identify the specific function of each option provided: Lectins, Selectins, Mectins, and Cadherins.
Recall that Lectins are a type of protein that bind specifically to certain sugars and play a role in cell-cell adhesion by recognizing and binding to carbohydrate structures on the cell surface.
Consider the role of Selectins, which are a type of CAM that also bind to carbohydrate structures on the cell surface, facilitating cell-cell adhesion, particularly in the immune system.
Evaluate the options based on their ability to bind to sugars on the plasma membrane, focusing on the known functions of Lectins and Selectins in this context.
