10 Questions
Why does red blood cell count increase at high altitudes?
To have more haemoglobin for oxygen to bind to due to fewer oxygen molecules at high altitudes.
How does carbonic anhydrase contribute to the transport of carbon dioxide in the blood?
By catalyzing the reaction that breaks down carbonic acid into water and carbon dioxide.
What is the purpose of the chloride shift process in red blood cells?
To help maintain the cell's electrical balance.
What happens to bicarbonate in the red blood cells during the transport of carbon dioxide?
Bicarbonate diffuses into the red blood cells and reacts with hydrogen ions to form carbonic acid.
Where does free carbon dioxide go after it is released from carbonic acid in the blood?
It diffuses from the blood into the lungs.
What direction do chloride ions move in the chloride shift process?
From the red blood cells into the plasma.
How does the saturation of haemoglobin change in response to decreased oxygen levels?
Haemoglobin saturation decreases as oxygen levels drop.
What is the role of haemoglobin in oxygen transport?
Haemoglobin binds to oxygen to transport it through the bloodstream.
How does the partial pressure of oxygen affect the production of red blood cells?
Decreased partial pressure of oxygen stimulates the production of more red blood cells.
What is the primary function of fetal haemoglobin?
To facilitate the transfer of oxygen from the mother to the fetus.
Learn about the role of carbonic anhydrase in catalyzing the reaction between carbon dioxide and water to produce carbonic acid, which leads to the release of hydrogen ions. Discover how hydrogen ions combine with haemoglobin to form haemoglobinic acid, promoting the dissociation of oxygen from haemoglobin.
