What does the given figure represent?
What does the given figure represent?
Options
- AThese structures of protein are an assembly of more than one polypeptide or subunit.
- BThe manner in which these individual folded polypeptides or subunits are arranged with respect to each other (e.g. linear string of spheres, spheres arranged one upon each other in the form of a cube or plate etc.) is called the quaternary structure of a protein.
- CAdult human haemoglobin is an example of quaternary structure of a protein.
- DAdult human haemoglobin consists of 4 subunits. Two of these are not identical to each other.Two subunits of α type and two subunits of β type together constitute the human haemoglobin (Hb).
Correct answer
D. Adult human haemoglobin consists of 4 subunits. Two of these are not identical to each other.Two subunits of α type and two subunits of β type together constitute the human haemoglobin (Hb).
Step-by-step solution
Some proteins are an assembly of more than one polypeptide or subunits. The manner in which these individual folded polypeptides or subunits are arranged with respect to each other (e.g. linear string of spheres, spheres arranged one upon each other in the form of a cube or plate etc.) is the architecture of a protein otherwise called the quaternary structure of a protein (Fig. 9.3 d). Adult human haemoglobin consists of 4 subunits. Two of these are identical to each other. Hence, two subunits of α type and two subunits of β type together constitute the human haemoglobin (Hb).
