A) Lipid-carbohydrate, carbohydrate-carbohydrate, lipid-lipid
B) Protein-lipid, lipid-lipid, protein-protein
C) Carbohydrate-carbohydrate, protein-carbohydrate, protein-protein
D) Lipid-carbohydrate, protein-lipid, carbohydrate-protein

Quizplus · Accepted Answer

Cell adhesion often involves interactions between proteins (such as cadherins and integrins) and carbohydrates (such as those found in the extracellular matrix), as well as protein-protein interactions. These interactions are crucial for the structure and function of tissues.
