Explore The Major Difference Between C3 And C4 Plants

The atomic mass of different isotopes affect their chemical kinetic behavior leading to natural isotope separation processes. For example different sources and sinks of methane have different affinity for the C and C isotopes which allows distinguishing between different sources by the C/ C ratio in methane in the air. In geochemistry paleoclimatology and paleoceanography this ratio is called δ C. The ratio is calculated with respect to Pee Dee Belemnite (PDB) standard:

The atomic mass of different isotopes affect their chemical kinetic behavior leading to natural isotope separation processes. For example different sources and sinks of methane have different affinity for the C and C isotopes which allows distinguishing between different sources by the C/ C ratio in methane in the air. In geochemistry paleoclimatology and paleoceanography this ratio is called δ C. The ratio is calculated with respect to Pee Dee Belemnite (PDB) standard: ‰ Similarly carbon in inorganic carbonates shows little isotopic fractionation while carbon in materials originated by photosynthesis is depleted of the heavier isotopes. In addition there are two types of plants with different biochemical pathways; the C3 carbon fixation where the isotope separation effect is more pronounced C4 carbon fixation where the heavier C is less depleted and Crassulacean Acid Metabolism (CAM) plants where the effect is similar but less pronounced than with C4 plants. Isotopic fractionation in plants is caused by physical (slower diffusion of C in plant tissues due to increased atomic weight) and biochemical (preference of C by two enzymes: RuBisCO and phosphoenolpyruvate carboxylase) factors. The different isotope ratios for the two kinds of plants propagate through the food chain thus it is possible to determine if the principal diet of a human or an animal consists primarily of C3 plants (rice wheat soybeans potatoes) or...
