Best Answer

There is no C2 plants, just C3, C4, and CAM plants - they have to do with the photosynthesis of the plant and how raw materials are transported.

C2 pathway is photo respiratory pathway where oxygen is fixed by RuBisCo instead of CO2( asin normal photosynthetic plants or C3 plants)

C2 because in photorespiration 2 carbon compound ( phosphoglycolate) is formed as a first product

C3 are normal phortosynthetic plants , called C3 because 1st product in cycle formed is 3 carbon compound ( 3- phosphoglycerate) and nrmal Calvin cycle continues

C4 plants are those which have evolved mechanism to overcome photorespiration and use PEP carboxylase to fix carbon

Is alfalfa a c-4 plant?

No, alfalfa is not a C4 plant. It is a C3 plant, which means it uses the C3 photosynthesis pathway. C4 plants have a different type of photosynthesis pathway that allows them to be more efficient in hot and dry conditions.

How does the hatch slack pathway compare with the Calvin cycle?

C3 carbon fixation or the Calvin cycle is a metabolic pathway for carbon fixation in photosynthesis. This process converts co2 and ribulose bisphosphate into 3-phosphoglycerate through the following reaction: 6 CO2 + 6 RuBP → 12 3-phosphoglycerate In C4 , carbon dioxide is drawn out of malate and into this reaction rather than directly from the air. Since every CO2 molecule has to be fixed twice, the C4 pathway is more energy-consuming than the C3 pathway. The C3 pathway requires 18 ATP for the synthesis of one molecule of glucose while the C4 pathway requires 30 ATP. But since otherwise tropical plants lose more than half of photosynthetic carbon in photorespiration, the C4 pathway is an adaptive mechanism for minimizing the loss.
