This reaction takes place in the cytoplasm, but the epinephrine reenters the granule after its methylation. WebA negative correlation between epinephrine and norepinephrine in HAPE-p is evident from the fact that norepinephrine is a major binder for alpha 1-adrenergic receptors, so much of it is binding to the receptors and thus less is available in case of HAPE-p to be converted to epinephrine. 35 Whereas in HAPE-c and HLs, the correlation was positive ... mit flight goggles on ati card
