- A neurotransmitter called "GABA" decreases the rate of action potential generation in neurons, but the effect can be overridden by excitatory neurotransmitters. Alcohol binds to the GABA receptor and has the same effect. Alcohol must Select one: a. Cause depolarization in neurons b. Cause hyperpolarization in neurons c. Block calcium entry at the axon terminus d. Block voltage-gated sodium channelsarrow_forwardCocaine affects a synapse by blocking the reuptake or reabsorbtion of the neurotransmitter dopamine by the presynaptic neurons. Therefore,the levels of dopamine continue to build in the synapse, causing certain effects on the body. A. Explain how cocaine interferes with neural transmission across the synapse B.Describe the natural role of dopamine in the brain C. Predict how cocaine could be addictive after only one use.arrow_forwardSarin nerve gas paralyzes muscle by interfering with neuronal transmission by which of the following? Select one: O A. encephalin O B. serotonin O C. acetylcholine O D. glutamate O E. GABAarrow_forward
- Both potassium and sodium channels located along the nerve membrane are voltage-gated. This means that they respond to the changes in the voltage by opening and closing the gates to allow the ions to flow in or out of the membrane. When the threshold level is reached and depolarization occurs, how come only the sodium ions begin to rush in? a. The threshold levels for both sodium and potassium channels are equal, but sodium channels are slower to open. b. The threshold levels for both sodium and potassium channels are equal, but potassium channels take longer to open. c. The threshold level for the potassium channels is lower than the sodium channels. d. The threshold level for the potassium channels is higher than the sodium channels.arrow_forwardWhich receptor is an adrenergic receptor that results in broncodialation when activated by agonist? a.
