A(n)________ consists of 3 fibrous protein subunits wound together like the strands of a rope; it is flexible, yet very strong when pulled by either end.
A) collagen fiber
B) parenchyma
C) elastic fiber
D) reticular fiber
E) fibroblast

Question

Quizplus · Accepted Answer

Collagen fibers are made up of three protein subunits that form a strong, rope-like structure. They are flexible and can resist tension, making them important components of connective tissue.

Option B) Parenchyma refers to the functional cells of an organ or tissue and is not related to fibrous protein subunits;

Option C) Elastic fiber is a stretchy protein that can recoil after stretching but is not composed of three fibrous protein subunits;

Option D) Reticular fibers are thinner and branched, forming a network to support the structure of organs but are not composed of three fibrous protein subunits;

Option E) Fibroblast is a type of cell found in connective tissue that synthesizes extracellular matrix components such as collagen fibers, but it is not a fiber itself.
