Question

Bicarbonate ions are produced inside
A. Basophiles
B. Neutrophils
C. Erythrocyte
D. Lymphocyte

Answer 1

Hint: Carbonic acid is important in the transport of carbon dioxide in the blood. Carbon dioxide invades blood in the tissues due to the fact that its native partial pressure is more than its partial pressure in blood transporting via the tissues.

Complete answer:
The capability of blood to bear carbon dioxide as bicarbonate is increased by an ion transfer system in the membrane of the red blood cell that at the same time transfers a bicarbonate ion away from the cell and inside the plasma in replacement for a chloride ion. The concurrent replacement of these two ions, called the chloride shift, allows the plasma to be utilized as a storage site for bicarbonate without changing the electrical charge of either the plasma or the red blood cell.

Now, let us find the solution from the option.
- Basophils secrete histamine during allergic reactions. Basophils are assumed to perform a role in giving rise in the body to generate the antibody known as immunoglobulin E (IgE). So they do not form any bicarbonate ion.
- Neutrophils show and secrete cytokines that increase inflammatory reactions by many other cell kinds and also neutrophils perform a main role in powerful defense against penetrating pathogens.
- In erythrocytes, which are also known as red blood cells, is the cell where bicarbonate ion production takes place. In the cell, some carbon dioxide binds to hemoglobin forming carbaminohemoglobin. Then the carbonic anhydrase enzyme found in red blood cells quickly converts carbon dioxide and water into bicarbonate and hydrogen ions.
 - Lymphocytes are white blood cells that are also one of the body's main types of immune cells. However they do not produce bicarbonate ions.

Thus, the correct option is C. i.e. Erythrocyte.

Note: Just twenty six percent of the net carbon dioxide content of blood subsists as bicarbonate with inside the red blood cell, whilst sixty two percent subsists as bicarbonate in plasma; but the bulk of bicarbonate ions is first generate in the cell, and then delivered to the plasma. An arrangement of reactions happens when blood reaches the lung, in which the partial pressure of carbon dioxide is less than inside the blood.
