- Which of the following statements concerning synapses is FALSE? O A) Modulation of synaptic strength can be presynaptic of postsynaptic B) High frequency stimulation in the presynaptic neuron often leads to DECREASED neurotransmitter release O C) Modulation of synaptic strength can either be short term, lasting seconds, or long term, lasting as long as a lifetime. D) Agonists are drugs that mimic neurotransmitters and antagonists are drugs that block the action of neurotransmitters O E) Certain drugs prevent the reuptake of neurotransmitter from the synapsearrow_forwardwhat is the function of cholinesterase in the synapse?arrow_forwardhow many molecules of neurotransmitter are in a synaptic vesicle?arrow_forward

- Cocaine blocks the removal of dopamine from the synapse, leading to a rapid rise of dopamine in the synapse. Which of the following best describes what will likely occur as a result of increased dopamine in the synapse? The presynaptic cell will be unable to release more neurotransmitter. the postsynaptic cell will return to its resting potential, causing feelings of well-being. The postsynaptic cell will be constantly activated, causing feelings of euphoria. The postsynaptic cell will respond more quickly to a change in output of the presynaptic cell, causing feelings of euphoria. The buildup of neurotransmitter will activate the presynaptic cell, causing feelings of euphoria.arrow_forwardDescribe the process of Removal of Neurotransmitters from the Synapse?arrow_forwardWhat is meant by a chemical synapse?arrow_forward
