Polymerization of collagen into large collagen fibers occurs:
A)in the endoplasmic reticulum.
B)in the Golgi complex.
C)in secretory vesicles.
D)extracellularly.

Question

Quizplus · Accepted Answer

Polymerization of collagen into large collagen fibers occurs extracellularly, after the collagen has been secreted and cleaved into tropocollagen monomers. The assembly of tropocollagen molecules into fibrils and fibers occurs through a complex process involving cross-linking and alignment of the individual molecules.
