  a. plasmin.
  b. fibrin.
  c. collagen.
  d. factor X.

Question 2

A 5-year-old male is diagnosed with a bacterial infection. Cultures of the bacteria revealed lipo-polysaccharides on the bacterial cell surface. Which of the complement pathways would be acti-vated in this case?
 
  a. Classical pathway
  b. Lectin pathway
  c. Alternative pathway
  d. Kinin pathway

Answer to Question 1

ANS: B
The end product of the clotting system is fibrin. Plasmin activates the complement cascade. Col-lagen plays a factor in wound healing. Factor X is a first step in the clotting system.

Answer to Question 2

ANS: C
The alternative pathway is activated by several substances found on the surface of infectious or-ganisms, such as those containing lipopolysaccharides . The classical pathway is primarily acti-vated by antibodies that are proteins of the acquired immune system. The lectin pathway is simi-lar to the classical pathway but is independent of antibody. It is activated by several plasma pro-teins. The kinin pathway is involved in coagulation.
