Carboxylation of the CO2 acceptor molecule. 

The first committed enzymatic step in the cycle is the reaction of CO2 and water with a five-carbon acceptor molecule (ribulose 1,5-bisphosphate) to generate two molecules of a three-carbon intermediate (3-phosphoglycerate).

Cytokinins are defined as compounds that have biological activities similar to those of trans-zeatin. These activities include the ability to do the following:

Induce cell division in callus cells in the presence of an auxin

Promote bud or root formation from callus cultures when in the appropriate molar ratios to auxin

Delay senescence of leaves

Promote expansion of dicot cotyledons
