Reserpine is a drug that can control high blood pressure by reducing the number of catecholamine neurotransmitters present in the synapse. Epinephrine, norepinephrine, and dopamine are examples of catecholamine neurotransmitters. One of the known side effects of reserpine is to cause the symptoms of Parkinson’s disease.
Parkinson's disease is associated with dopamine. Parkinson's disease occurs when the nerve cells in the part of the brain that controls muscle movement are gradually destroyed and the neurons can no longer produce dopamine to coordinate muscle movements.
Reserpine causes symptoms by
a. inhibiting the release of dopamine from the presynaptic neuron
b. blocking the dopamine receptor in the postsynaptic neuron
c. breaking down the neurotransmitter acetylcholine in the synapse
d. breaking down cholinesterase enzyme in the synapse
Which of the following substances acts as a neurotransmitter?
catechol
O norepinephrine
O dopamine
more than one response is correct
One of the following does not belong to the group. Identify the one and explain why it does not belong:
Dopamine
Epinephrine
Norepinephrine
Acetylcholine
Serotonin
