Final answer:
C. Hemoglobin with carbon dioxide bound to it. Carbaminohemoglobin is hemoglobin with carbon dioxide bound to it, allowing for the transport of carbon dioxide in the bloodstream. This compound allows for the transport of carbon dioxide from the tissues to the lungs, where it can be exhaled.
Step-by-step explanation:
Carbaminohemoglobin is hemoglobin with carbon dioxide bound to it. When carbon dioxide enters the bloodstream, it forms a reversible reaction with the amino acid moieties on the globin portions of hemoglobin, creating carbaminohemoglobin. This compound allows for the transport of carbon dioxide from the tissues to the lungs, where it can be exhaled. Unlike oxygen, carbon dioxide does not bind to the iron in hemoglobin, but rather to the amino acids.
Carbaminohemoglobin is a compound formed when carbon dioxide (CO2) binds to hemoglobin. As blood circulates through the tissues, carbon dioxide produced by cellular metabolism is transported in the bloodstream. Some of this carbon dioxide binds to hemoglobin in red blood cells, forming carbaminohemoglobin. When carbon dioxide enters the bloodstream, it forms a reversible reaction with the amino acid moieties on the globin portions of hemoglobin, creating carbaminohemoglobin. The majority of carbon dioxide is transported in the blood in the form of bicarbonate ions, but a smaller fraction is carried directly bound to hemoglobin.
