In c4 plants sugar is synthesized in

WebThe drawback to C4 photosynthesis is the extra energy in the form of ATP that is used to pump the 4-carbon acids to the bundle sheath cell and the pumping of the 3-carbon compound back to the mesophyll cell for conversion to PEP. This loss to the system is why C3 plants will outperform C4 plants if there is a lot of water and sun. WebJul 18, 2024 · Addition of sugars from C4 plants (sugarcane, maize) can be reliably detected by the EAIRMS method with a sensitivity of 7%. Therefore, the difference between the carbon isotope ratio of the protein extract and of honey will provide an exact measure of any minimum level of adulteration.

WebC4 photosynthesis minimizes photorespiration and enhances sugar production. C4 plants thrive in hot regions with intense sunlight. A second strategy to minimize photorespiration is found in succulent plants, cacti, pineapples, and several other plant families. These plants are known as CAM plants for crassulacean acid metabolism. WebSep 14, 2024 · In C4 plants, PEPC, OMT, NADP-MDH, PPDK, and carbonic anhydrase (CA) are expressed specifically in mesophyll cells, whereas RuBisCO, DIT1, and NADP-ME are expressed preferentially in the BS ( Weber and von Caemmerer, 2010; Gowik et al., 2011 ).
