Which product is formed when carbon dioxide combines with the amino group of hemoglobin?
Correct answer: A. Carboxyhemoglobin
- A. Carboxyhemoglobin
- B. Plasma proteins
- C. Bicarbonate ions
- D. Histamines
Explanation
When carbon dioxide (CO2) combines with the amino group of hemoglobin, the product formed is "Carboxyhemoglobin." Carboxyhemoglobin is a compound that forms when carbon dioxide binds to hemoglobin in red blood cells. This compound is formed during the process of gas exchange in the lungs, where carbon dioxide is transported from the tissues to the lungs to be expelled from the body. Carboxyhemoglobin is important in the context of carbon monoxide poisoning, as carbon monoxide (CO) can bind to hemoglobin in a similar manner, reducing the oxygen-carrying capacity of the blood.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
