Question
Chapter 48.4, Problem 1CC
Summary Introduction
To explain: The neurotransmitter ability to produce opposite effects in different tissues.
Concept introduction:
The ligand–gated ion channel that binds and responds to a neurotransmitter is called as ionotropic receptor. Binding of the neurotransmitter to its receptor opens the channel and allows either all or only particular ions to diffuse through the membrane.

An MAO inhibitor type of antidepressant is functioning at an active dopaminergic synapse that increases the rate of sodium flowing into the cell. b.) Prozac is present at an active serotonin synapse where receptor activation increases the flow of potassium out of the cell.arrow_forwardWhat is the role of a neurotransmitter?

Why not a few receptors and lots ofneurotransmitters acting on each receptor?arrow_forwardReserpine 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 synapsearrow_forward
