I: | GLUT-4 | Enables glucose transport out of the cells |
II: | Collagen | Most abundant protein in animal world |
III: | RuBisCO | Most abundant protein in the whole of the biosphere |
1. | Only I | 2. | Only I and II |
3. | Only I and III | 4. | Only II and III |
The first amino acid in the primary structure of a protein is termed as:
1. | C – terminus amino acid | 2. | N – terminus amino acid |
3. | An imino acid | 4. | Alpha amino acid |
Quaternary structure is seen in proteins that:
1. act as biochemical catalysts
2. are embedded within the plasma membrane
3. are assembly of more than one subunits
4. do not have any structural role in the cell
An alpha helix is a:
1. primary structure of a protein
2. secondary structure of a protein
3. tertiary structure of a protein
4. quaternary structure of a protein
