Answer:
<h2>Its true!!</h2>
Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!
Answer: its in the center
Explanation:
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.

c. run faster is the correct option
Primates have large brains and dexterous limbs. Non-primates have small brains and inflexible limbs. The main differences between primates and non-primates are the size of the brain and the flexibility of the limbs.
Humans are primates and are a diverse group containing about 200 species. Monkeys, lemurs, and apes are our cousins, and we have all evolved from a common ancestor over the last 60 million years.
Primates: Humans, apes, monkeys, chimpanzees, gorillas, baboons, and orangutans are examples of primates.
Non-primates: Birds, reptiles, amphibians, and some mammals are not primates.
