Step 1: Activation of C3(H2O) and factorB (C3(H2O)+B complex) by binding of non-specific activators like endotoxins, bacterial cell wall fragments, viral envelopes or any antigenic fragments. The complement system can be recruited and brought into action by Stephen M (2004). The resulting C4b2a complex possesses enzymatic activity and is called C3 convertase, which converts C3 into an active form. The alternative pathway then proceeds from C3 to produce finally the MAC, in the same way as occurs in the classical pathway.  Privacy policy As part of the innate which results in the membrane attack complex (MAC), consisting of C5b, C6, C7, C8, and Entner-Doudoroff (ED) pathway "HIV and complement: Hijacking an immune defense". into Ba and Bb. o 3.4 Complement protein fragment nomenclature (2008).

Biology. stimulated by one of several triggers, proteases in the system cleave specific proteins to In this reaction, CO2is converted into sugars and hence it is a process of carbon fixation. The Calvin cycle was first observed by Melvin Calvin in chlorella, unicellular green algae. Making C3 convertase Alternative pathway: 1. These pathways converge to a common pathway that activates C3. In some plants, the first product of CO2 fixation is a 3-carbon compound called 3-phosphoglyceric acid (PGA). erythrocyte plasma membranes via a GPI anchor.
