Fibrous structural proteins of the extracellular matrix are embedded in gels formed from polysaccharides called
A) elastin.
B) fibronectin.
C) glycosaminoglycans (GAGs).
D) laminin.

Question

Quizplus · Accepted Answer

Fibrous structural proteins like collagen and elastin are embedded in polysaccharide gels called glycosaminoglycans (GAGs), which provide hydration and support to the matrix. Fibronectin and laminin are other structural proteins found in the extracellular matrix, but they do not form the gels in which the fibrous proteins are embedded.
