D) reticular fibers.

Question

Quizplus · Accepted Answer

Glycosaminoglycans (GAGs) and proteoglycans are major components of the ground substance, which is a gel-like substance that fills the spaces between cells and fibers in connective tissue. GAGs are long, unbranched polysaccharides that attract and bind water, providing the ground substance with its lubricating and shock-absorbing properties. Proteoglycans are proteins that are covalently attached to GAGs, forming large complexes that further contribute to the structural and functional properties of the extracellular matrix. While GAGs and proteoglycans may also be present in blood and involved in inflammation, they are most commonly associated with the ground substance. Reticular fibers, on the other hand, are composed of a different type of protein and are not directly related to GAGs or proteoglycans.
