All of the following factors are responsible for unloading of oxygen from the hemoglobin molecule except
tatuchka [14]

All of the factors are responsible for unloading of oxygen from the hemoglobin molecule except the increase in partial pressure of oxygen.

Because the affinity of haemoglobin for binding oxygen increases as  partial pressure of oxygen rises.

<h3>What is  Haemoglobin?</h3>

Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs.

<h3>What are factors that affect Haemoglobin's affinity for oxygen?</h3>
  • When used as an oxygen transporter, hemoglobin can carry about 65 times as much oxygen as simple solution in plasma could.
  • A cooperative oxygen-hemoglobin affinity is produced by conformational changes in the molecule.
  • The oxygen-hemoglobin dissociation curve's sigmoidal form reflects this characteristic.
  • Temperature, hydrogen ions, carbon dioxide, and intraerythrocytic 2,3-DPG all have an impact on hemoglobin's affinity, and they all interact with one another.

Answer:

GUA and GUG.

Explanation:

If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.

Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.

Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.

alex41 [277]

Answer: c. when she ends the diet she regains additional body fat.

Explanation:

Obesity can be defined as a genetic disorder in which the body obtains and retains too much amount of body fat. It is different from being overweight.

Obesity happens when the person obtains more amount of calories in the food then actually burned through work or exercise. Obesity increases the risk factor for arthritis, stroke and cancer.

Here, in the given situation, ending up diet is the likely cause of regaining weight again. As the unstable diet is likely to add more calories then actually utilized by the body and will be retained as fat.
