The photosynthetic pathways of C3, C4, and CAM are known to have different photosynthetic properties (Larcher, 1995; Nobel, 1991).Although the dry matter accumulation rate of CAM plants is lower than that of C3 and C4 plants, CAM plants have the ability to adapt to extreme environments such as drought, high temperature, and salt stress (Osmond, 1978; Rascher et al., 1998; Winter and Holtum, 2007). The labeling patterns were the same for cells grown at near-ambient (380 μ L L−1) and low (100 μ L L−1) CO2 concentrations. C4 pathway, is therefore, of adaptive advantage. C3 pathway in plants. 5) E-mail: dway4@uwo.ca. The C3 cycle is also called the photosynthetic carbon reduction (PCR) cycle and Calvin Cycle, after Melvin Calvin, an American biochemist.Calvin headed the research effort at the University of California which, with the use of radiolabeled 14 CO2, finally detailed the sequential reactions leading to the conversion of inorganic, atmospheric CO2 into carbohydrates and other organic compounds. Alternative Pathway • C3 is an unstable molecule continually undergoing hydrolysis in the blood and lymph. Once C3 is activated to C3b, it exposes a reactive thioester that allows the peptide to covalently attach to any surface that can provide a nucleophile such as a primary amine or a hydroxyl group.
