Such immunoglobulin-mediated binding of the complement may be interpreted as that the During the one-step process, the enzyme RuBisCO (ribulose bisphosphate carboxylase/oxygenase) causes an oxidation reaction in which some of the energy used in photosynthesis is lost in a process known as photorespiration. ; Rappaport, J. We already learnt that photosynthesis has two types of reactions – light reactions and dark reactions (Calvin cycle). title=Complement_system&oldid=825991256" 5 : 26. doi:10.1186/1742-2094-5-26.

Making C3 convertase Alternative pathway: 1. o Polyclonal antibodies to further damage the body. (iii) Production of C5 convertase: C3 is almost very similar to C4. C1q binds directly to the surface of the pathogen. The alternative pathway then proceeds from C3 to produce finally the MAC, in the same way as occurs in the classical pathway. adaptation of microbial pathogens to vertebrate immune defenses).
