In the context of cell-cell adhesion, which cell-surface molecules are primarily responsible for cell-to-cell recognition during tissue formation and immune interactions?

• A. Mitochondria, which signal recognition by releasing ATP into the extracellular space
• B. Cell adhesion molecules (CAMs), such as cadherins and selectins, that mediate specific binding between cells
• C. Lysosomes, which recognize other cells by secreting digestive enzymes to the cell surface
• D. Ribosomes, which identify neighboring cells by matching mRNA sequences across membranes

Answer: (B)
