Question

Are biogenic amine neurotransmitters such as dopamine considered to be proteins? No, it simply means that dopamine has at least one amine functional group in its molecular structure. No, dopamine cannot be a protein since proteins do not exhibit neurotransmitter activity. Yes, dopamine is a protein because of its expression of a nitrogen-containing amine group. Yes, amines are naturally occurring organic compounds composed of amino acids. Prozac belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), which block the removal of serotonin from its receptor, thereby enhancing a patient's mood. What mechanism allows serotonin to remain on its receptors longer? SSRIs are not as easily degraded by acetylcholinesterase, which allows them to remain on their receptors for an extended period of time. SSRIs inhibit the reuptake of serotonin back into the presynaptic neuron, which increases the level of serotonin in the synaptic cleft. SSRIs cause an increased number of serotonin receptors expressed on the presynaptic neuron membrane. SSRIs prevent the release of serotonin by making a permanent neurotransmitter-receptor complex on the postsynaptic membrane.

Answer 1

The correct nswer is A). No , it simply means dopamine has atleast one amine group. It is derived fro tyrosine which is a amino acid however we cannot classify them as proteins.

The correct answer is B, srris inhibit the reuptake of seratonin back into the presynaptic neuron, which increases the levels of seretonin in the synaptical cleft
