The extra cellular matrix on most connective tissues is made up of predominantly fibers and what?

The correct answer will be - proteoglycans and the glycoproteins

Explanation:

The connective tissue forms a very large proportion of the total mass of a body. The connective tissue plays a distinct role in the body like the movement of the cell, mechanical support, wound healing but the main role is to connect different tissues of the body.

The property of the connective tissue is determined by the amount and type of the extracellular matrix present which contains three main components which are the fibres like collagen, glycoproteins and the proteoglycans.

Thus, proteoglycans and glycoproteins are the correct options.
