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
Collagen, keratin, and elastin are fibrilar proteins.
Elastin is a globular protein, actually an enzyme, that breaks down proteins, such as elastin. It is a protease. In humans, there are eight different genes for the production of elastase. Elastase also has an important immunological role
.
Identifying the minerals that compose the rocks is concerned with the chemical compounds within the rocks, while the identification of the rocks is based on the processes that produced the rocks.
