Webremains in the synapse in high concentration Cocaine is a reuptake inhibitor that binds with the transporters, and therefore, blocks the reabsorption of the dopamine that has not been absorbed by the postsynaptic cell membrane. This results in a high concentration of dopamine in the synapse. Websynapse in response to an action potential Figure 2. Model of a typical action potential in a neuron Acetylcholine is a neurotransmitter that can activate an action potential in a postsynaptic neuron (Figures 1 and 2). A researcher is investigating the effect of a particular neurotoxin that causes the amount of
WebCholinesterase is a family of enzymes present in the central nervous system, particularly in nervous tissue, muscle and red cells, which catalyze the hydrolysis … WebThe transmitter binds to a receptor on the postsynaptic membrane and effects a cascade of events, resulting in the opening of ion channels. These lead to graded potentials, which may set up an action potential. 1) action potential sweeps down presynapatic axon. 2) calclium channels open in axon terminal.
