Question

Myoglobin can be analysed for its quaternary structure.
(A) True
(B) False

Answer 1

Hint: Myoglobin is a monomeric proton found in muscle tissue.
It is an oxygen binding protein found in coordinate and skeletal muscles.

Step by step answer: Myoglobin was the first protein whose structure was determined.
It is a monomeric protein. It is a smaller monomer of polymeric structure. It is a globular protein with a prosthetic group in the center.
The iron is located at the center and interacts with six ligands.
Secondary structure of myoglobin is unusual in that it contains a very high protein of -helical secondary structure.
The tertiary structure of myoglobin is typical water soluble globular protein.
Primary structure only includes the order of amino acids.
Quaternary structure of a protein involves the assembly of subunits.
Myoglobin is a functional single sequence. Since, myoglobin does not have multiple subunits, it does not have quaternary structure.
Myoglobin can be analyzed for its quaternary structure.

Therefore, from the above explanation the correct option is (A) True.

Additional Information:: Myoglobin is a monomeric protein that has the amino acids reduced.
It consists of eight -helical connected through an oxygen binding site.
It has a globular structure.
Myoglobin can exist in oxygen free form deoxymyoglobin or in a form in which it can exist in the oxygen free form, deoxymyoglobin.
Myoglobin binds oxygen well when concentration of oxygen is very high. It can bind oxygen more efficiently in muscle tissue.
This is important when the body is starved for oxygen such as during aerobic exercise.

Note: Myoglobin, an iron-containing protein in muscle, receives oxygen from red blood cells and transports it to the mitochondria of muscle cells where the oxygen is used in cellular respiration to produce energy.
