What is the primary role of ceruloplasmin?
1) Transport of copper
2) Anti-inflammatory activity
3) Lipid metabolism
4) Blood clotting
Ceruloplasmin is a protein synthesized in the liver that primarily functions to transport and regulate the levels of copper in the bloodstream. It is not directly involved in blood clotting or inflammation.
What is the primary function of the ATP7B protein in the context of Wilson's disease?
1) Copper uptake in the gut
2) Copper incorporation into ceruloplasmin
3) Copper excretion from hepatocytes
4) Copper metabolism in erythrocytes
The ATP7B protein is essential for copper excretion from hepatocytes into bile, and its deficiency leads to copper accumulation in the liver and other tissues in Wilson's disease.

Which of the following is the primary function of protein C?
1) Activation of factor V
2) Inhibition of factor Xa and thrombin
3) Formation of fibrin
4) Inhibition of factor VIIIa
Protein C is a vitamin K-dependent plasma protein that acts as an anticoagulant. Upon activation, it forms a complex with protein S and inhibits factor Xa and thrombin, thereby preventing excessive clot formation and promoting clot dissolution.
