- A single glutamatergic neuron (EPSP) becomes activated and sends glutamate to a post- synaptic neuron. That post-synaptic neuron, however, does not generate an action potential. Give a reason why an action potential is not generated in the postsynaptic neuron. Edit View Insert Format Tools Table 12pt v Paragraph v BIU T? vTyrosine came from the Greek word "tyros" which means cheese as it was discovered in cheese by Justus von Liebig, a German chemist in 1846. Tyrosine serves as the precursor for dopamine - the neurotransmitter which is considered as the "reward or pleasure molecule" in our brain. It is also involved in controlling the fine motor movement of our muscles such as those of our hands. Draw the titrimetric profile of tyrosine and calculate its isoelectric pH. [Note: The aromatic hydroxyl group is titratable]The efferent fibers of somatic nervous system are located in the CNS which regulated skeletal muscle contraction. * F T
