C) proteoglycans
D) elastin fibers.

Question

Quizplus · Accepted Answer

Collagen fibers are the primary extracellular molecules responsible for resisting tension in connective tissues. They are strong and provide tensile strength to the tissue. Intermediate filaments in fibroblasts are important for maintaining cell shape and integrity, but they do not contribute significantly to tissue resistance. Proteoglycans and elastin fibers play roles in other aspects of tissue function, such as compressibility and elasticity, respectively, but do not primarily resist tension.
