Questions: Which set of membrane proteins in the figure depicts an interaction between two separate cells? A B C D

Solution Steps

• A: Shows a protein using ATP to transport ions across the membrane, indicating active transport.
• B: Depicts a protein facilitating the movement of molecules through the membrane, suggesting facilitated diffusion.
• C: Illustrates two proteins from adjacent cells connecting, indicating cell-cell interaction.
• D: Shows a protein binding to a molecule, likely a receptor-ligand interaction.

• A: Involves ion transport within a single cell.
• B: Involves molecule transport within a single cell.
• C: Involves two proteins from adjacent cells connecting, indicating interaction between two separate cells.
• D: Involves receptor-ligand interaction within a single cell.

• Based on the analysis, set C depicts an interaction between two separate cells.
