The principal mechanism of MAO inhibitor action isB
a. Blocking the amine reuptake pumps, which permits to increase the concentration of the neurotransmitter at the receptor site b
b Blocking a major degradative pathway for the amine neurotransmitters, which permits more amines to accumulate in presynaptic stores.
c) Inhibition the storage of amine neurotransmitters in the vesicles of presynaptic nerve endings.
d) Antagonism of alfa2-norepinephrine receptors
