In human physiology, the blood protein fibrinogen is necessary for which process?
A
Catalysis of peptide bond hydrolysis in the stomach
B
Transport of oxygen in red blood cells
C
Maintenance of plasma oncotic pressure as the primary plasma protein
D
Formation of fibrin during blood clotting (coagulation)
Verified step by step guidance1
Understand the role of fibrinogen in human physiology by identifying its primary function among the options given.
Recall that fibrinogen is a soluble plasma protein produced by the liver and circulates in the blood.
Recognize that fibrinogen is converted into fibrin by the enzyme thrombin during the blood clotting (coagulation) process.
Note that fibrin forms a mesh that stabilizes the blood clot, preventing excessive bleeding.
Conclude that fibrinogen is necessary for the formation of fibrin during blood clotting, not for peptide bond hydrolysis, oxygen transport, or maintaining plasma oncotic pressure.
