WebHuman Biology 13th Edition Sylvia Mader that can be your partner. Thank you very much for reading Human Biology 13th Edition Sylvia Mader. Maybe you have knowledge that, … WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3. In the two other known pathways, C 4 and CAM (crassulacean acid metabolism), the C 3 pathway follows the fixation of CO 2 into oxaloacetate, a four-carbon acid, and its reduction to malate. PGA is formed from 2-carboxy-3-keto-D-arabinitol 1,5-bisphosphate ...
