Question

16.Globular proteins fold up into compact, spherical structures that have uneven surfaces. They tend to form

multisubunit complexes, which also have a rounded shape. Fibrous proteins, in contrast, span relatively large

distances within the cell and in the extracellular space. Which protein is not classified as a fibrous protein?

(a)elastase (b)collagen (c)keratin (d)elastin

Answer 1

The answer is A: elastase

Step-by-step explanation:

Fibrous proteins are insoluble, long, rod-like structured proteins that have high α-helix or β-sheet content, and are made up of a repeating motif. They are mechanically strong, cross-linked and play structural roles in the extracellular matrix. Examples are: collagen, keratin and elastin.

Answer 2

Answer:(a)elastase

Step-by-step explanation:

Elastase is a protease enzyme the function involves the cleavage of peptide bonds after amino acids with small side chains. This is responsible for cleaving the peptide bonds between the elastin fibers and aids in digestion of the elastic protein.

Thus the elastase cleaves the protein fibers this can be said that the elastase is a non-fibrous protein.
