Which of the following statements regarding proteoglycans is FALSE? Proteoglycans help tissues resist mechanical compression. Pr
oteoglycans are a major component of compact, dense connective tissues like bone. The negative charge associated with proteoglycans attracts cations, which cause water to be sucked into the extracellular matrix. Proteoglycans are comprised of a core proteins with many glycosaminoglycan polysaccharide chains covalently linked to it. The glycosaminoglycans are very hydrophilic and therefore extend out to fill a large amount of space in the extracellular matrix.
Proteoglycans are a major component of compact connective tissues but are relatively unimportant in watery tissues such as the jellylike substance in the interior of the eye.
Explanation:
these are protein that is divided into two classes which are called large ans small Proteoglycans.
The large proteoglycans has a large number of highly sulfated glycosaminoglycan side-chains that tends to hold water and whereby making the tendon to resist compression while the small proteoglycans are known to have a relationship with collagen fibrils which are known to regulate collagen fibril diameters. they help in signal regulation usually from the angle of intracellular compartments. the are known great for their large diversity especially in terms of different cores and different numbers of GAGs with different lengths and composition.
As long the progression of the cell to the M phase of the cell cycle is controlled by the chemical signals in the cytoplasm, then a cell in early M phase fused with a cell in G1 would result in the chromatin in prep of nuclear division in both cells to be condensed.
