In neuromuscular junction, the effect of acetylcholine (ACh) binding to receptors o nthe motor end plate lasts only briefly due to:_______
Rapid uptake of the ACh into the myofiber
Endocytosis of the ACh receptor into the myofiber
Rapid destruction of ACh in the synaptic cleft by acetylcholinesterse
Rapid destruction of ACh in the synpatic cleft by monoamine oxidase
Diffusion of the ACh out of hte synaptic cleft
