Solution

(1) Apical surface is the surfaces of intestinal epithelial cells that face the lumen of the intestine. Basolateral surface is the surfaces of intestinal epithelial cells that face the circulatory system.

(2) Fibronectins occurs widely throughout supporting tissues and body fluids, Laminins are found mainly in the basal laminae.

(3)These are transmembrane proteins that serve as receptors for ECM proteins such as collagen, fibronectin, and laminin; selectin is the best-characterized Integrin

(4)The glycocalyx is a carbohydrate-rich zone juxtaposed between the plasma membrane and the ECM of many types of animal cells.

(5)The groups mediate cell-cell recognition and adhesion; the two groups of proteins can be distinguished from each other-functionally because of the calcium requirement of Cadherins but not IgSFs.

(6)Collagen is responsible for the strength of the ECM, whereas elastin imparts elasticity and flexibility to the ECM.
