Simplified biosynthetic pathway for cytokinin biosynthesis followed given such steps;

a) isopentenyl transferase (IPT), is the addition of the isopentenyl side chain from DMAPP (dimethylallyl diphosphate) to an adenosine moiety (AMP)

b) iPRTP or iPRDP is converted to ZTP or ZDP respectively by cytochrome P450 monooxygenase  and eventually is converted to zeatin

c) The ribotide and riboside forms of trans-zeatin can be interconverted, and free transzeatin can be formed from the ribotide by the LONELY GUY (LOG) family of cytokinin

Which of the following steps is true of the cytokinin biosynthesis?
