Summary Introduction
To determine:
The similarities and differences in the structures and functions of cadherins and integrins proteins found in animal cells.
Introduction:
In a multicellular organism, cells are linked to each other by specialized structures called cell junctions. Three types of junctions found between cells in animals are anchoring junctions, tight junctions, and gap junctions.

The red arrow indicates the amino acid lysin (K) that binds to the oxygen of the retinol (indicated by the blue arrow). The purple arrow indicates the retinal bound to the rhodopsin. In healthy individuals, retinal is abundant and can binds to the rhodopsin, making it functional (light-sensitive).
