Give comparison between the following: - C3 and C4 pathways
|C3 pathways||C4 pathways|
|1||Ribulose biphosphate is the first accepter of CO2||1||Phosphoenol pyruvate is the first accetor of CO2, while ribulose biphosphate is second acceptor|
|2||Phosphoglyceric acid is the first product.||2||Oxaloacetic acid is the first product.|
|3||The plants operate only Calvin cycle||3||Plants operate a dicarboxylic acid cycle in addition to Calvin cycle.|
|4||CO2 compensation point is 25 - 100 ppm.||4||CO2 compensation point is 0 - 10 ppm|
|5||Mesophy II cells perform complete photosynthesis.||5||Mesophy II cells perform only initial fixation.|
|6||The rate of carbon assimilation is slow||6||The rate of carbon assimilation is quite rapid|
|7||The plant are unable to perform photosynthesis at very low CO2 concentration (say 10 - 50 ppm)||7||Photosynthesis continues even at very low CO2 concentration of 10 - 50 ppm|
|8||The cycle operate in all plants||8||The cycle is found only in some plants like maize, sugarcane etc.|
|9||Fixation of one molecule of CO2 uses 3 ATP and 2NADPH||9||Fixation of one molecule of CO2 required 5 ATP and 2NADPH|
