Following are certain statements regarding C3, C4 and CAM plants

a.) The atmospheric CO2 assimilates into the single cell C4 cycle diatoms, C4 conc. Is higher at the external side where the C3 conc. Is higher at the internal side where the CO2 assimilation takes place and the transport to the vascular tissue

b.) In mitochondria, two molecules of glycine yield a molecule of serine with the concurrent release of CO2 and NH4+ by the successive action of the glycine decarboxylase complex Only

c.) Plant with the C4 metabolism need less rubisco than C3 plants to achieve a given rate of Photosynthesis

d.) CAM Plant PEP Case only active during the Dark due to its phosphorylation while C4 PEP Case active throughout the day
