Synthesize the sequence of events that lead to the formation of C3 convertase in the lectin pathway.

Mannose-binding lectins bind to mannose, which then activates C3 convertase through a protease cascade.

MBLs activate antibodies to form C3 convertase.

MBLs bind to C3 convertase directly on pathogen surfaces.

MBLs directly cleave C3 into C3a and C3b.
