In muscle, glycogen phosphorylase kinase can be activated by nerve stimulation even in the absence of hormonal signals. Nerve stimulation alone results in activation of glycogen phosphorylase kinase as a result of:

Some given statements about  the cytokinin signalling pathway;

a)  Cytokinin receptor CRE1 probably functions as a monomer

b) Two other hybrid sensor kinases (AHK2 and AHK3) may also act as cytokinin receptors in Arabidopsis

c) Activated receptor activates their histidine kinase activity, The phosphate is transferred to an aspartate residue (D) on the fused receiver domains

d) The phosphate is then transferred to a conserved histidine present in an AHP protein that transfer the phosphate to an aspartate residue  located within the receiver domain of type-B ARRs only

e) The phosphorylation of the type-B ARR activates the output domain to induce transcription of genes encoding type-A ARRs.

f) The phosphorylated type-A ARRs feed back to negatively regulate cytokinin signaling, thus dampening cytokinin responses
