Let us say the protein hemoglobin was created. The polypeptide created will now need to merge with 3 more polypeptides to create
a Quaternary Structure protein before it gets sent to the blood. What will this polypeptide need to do BEFORE it exits the cell via exocytosis to go do its job?
The actions required by hemoglobin before exiting the cell to perform its action include subtle changes regarding the arrangement of the subunits.
Explanation:
Human hemoglobin, the protein responsible for carrying oxygen across the blood, chas a quaternary structure which consists of two subunits of one type (designated α) and two subunits of another type (designated β). The rearrangement of the structure is required so that the hemoglobin can absorb oxygen with greater efficiency. These changes are generally subtle and involve in the arrangement of the subunits.
