Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Is collagen ____
A
tough
B
flexible
C
weak
D
None of the above
Explanation: 

Detailed explanation-1: -Rather collagen appears to be a very flexible component of the extracellular matrix. Potential for management practices to alter collagen characteristics therefore exists.

Detailed explanation-2: -The results confirm that type I collagen monomer is flexible rather than rigid, rod-like molecule. Such flexibility may possibly be a consequence of the micro-unfolding of discrete domains of single collagen molecule.

Detailed explanation-3: -Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the movement of the body.

Detailed explanation-4: -Collagen is unique in the sense that it remains soft and flexible under low stress and becomes stiffer when stress is increased. Collagen therefore ensures that the body’s cells are able to withstand a certain degree of internal and external stress.
