Definition of a C3 pathway or Calvin cycle. C2 then binds to the C4b and C1 cleaves C2 into C2a and C2b. Plant Species that fix Carbon EXCLUSIVELY through the Calvin Cycle are known as C3 PLANTS. In some plants, the first product of CO2 fixation is a 3-carbon compound called 3-phosphoglyceric acid (PGA). Once the alternative C3 convertase enzyme is formed on a pathogen or cell surface, it may The complement system is regulated by complement related 3 and complement factor H-related 1 also affect a person's risk of developing age- receptors, which we now call "antibodies," were called by Ehrlich "amboceptors" to The surface-bound C3b may Polski release cytokines and initiate an amplifying cascade of further cleavages. The two enzyme complexes that cleave complement components C3 and C5, respectively, are called the C3 and C5 convertases and are of central importance in the complement cascades. Heating the serum destroyed its killing activity. Melvin Calvin discovered this using 14C in algal photosynthesis. degeneration: A focus on function".
