Question

Quizplus · Accepted Answer

The majority of norepinephrine (NE) is taken back up into the presynaptic terminal (re-uptake) to be recycled and used again in future signaling. The precursor for NE is dopamine, which is synthesized in the presynaptic terminal and then enzymatically converted to NE. Therefore, the correct answer is D – NE is taken back up into the presynaptic terminal and its precursor is dopamine.
