Answer :
Final answer:
The lectin complement pathway is activated by the interaction of microbial carbohydrates with mannose-binding lectin (MBL) or ficolins found in the plasma and tissue fluids. The alternative complement pathway is activated by the binding of C3b to microbial surfaces and antibody molecules. Therefore, the complement pathway activated by mannose-binding lectins is the lectin pathway.so,the correct option is:d. lectin pathway.
Explanation:
The lectin complement pathway is activated by the interaction of microbial carbohydrates with mannose-binding lectin (MBL) or ficolins found in the plasma and tissue fluids. When lectins bind to carbohydrates on the surface of a pathogen, they trigger the activation of complement proteins, leading to the formation of the complement protein C3. This pathway is known as the lectin pathway because it is initiated by the binding of mannose-binding lectins.
The alternative complement pathway, on the other hand, is activated by the binding of C3b to microbial surfaces and to antibody molecules. Activation of this pathway leads to the formation of the complement protein C3 as well. Therefore, the complement pathway that is activated by mannose-binding lectins is the lectin pathway.
