Final answer:
Cadherins are responsible for cell-cell adhesion, forming the 'glue' that binds cells into tissues, while ATP stores and transfers energy within cells.
Step-by-step explanation:
The molecule that provides cell-cell adhesion is B) Cadherins. Cadherins are proteins that are involved in binding cells together. They are an essential component of adherens junctions (desmosomes), acting as the 'glue' that holds cells together to form cohesive tissues and sheets of cells. On the other hand, when considering potential energy in molecules, ATP (Adenosine triphosphate) is likely to have the most potential energy compared to ADP, glucose, and sucrose because it stores energy for use by body cells and is involved in energy transfer within the cell.
