(Redirected from Adhesion molecules). Cell adhesion molecules (CAM s) are proteins located on the cell surface involved in binding with other cells or with the extracellular matrix (ECM) in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings.
Cohesion is the attraction between molecules of the same substance. For ex. when water molecules tend to stick together. Cohesion is what allows spiders and other insects â¦to walk ON water. Adhesion on the other hand, is the attraction between molecules of different substances.
