classic synaptic neurotransmission - answer-Presynaptic to synaptic to post synaptic retrograde neurotransmission - answer-Neurotransmitter moves to opposite direction from post synaptic to presynaptic Used to limit a response volume transmission - answer-Neurotransmitter spills over to other synapses by diffusion signal transduction cascade - answer-Triggered by chemical neurotransmitter from presynaptic neuron -Ligand binds to receptor which is activated to bind to G-protien and series of messengers ultimate goal of signal transduction cascade - answer-ultimate goal is to turn off or on gene (GENE EXPRESSION) and production of phosphoprotien ultimate targets of signal transmission - answer-to turn on or turn off genes (Gene Expression) and to produce phosphoprotienssecond messenger - answer-change occurs to bind to G-protien -which changes to bind to enzyme -which changes and forms second messenger 2nd messenger found? - answer-Intracellular G-linked protein - answer-Activated by binding to receptor after receptor has been conformational changed by neurotransmitter. G-linked protein's role? - answer-Once bound to receptor G-linked protien changes shape and binds to enzyme which then release second messenger to next enzyme in signal transduction cascade. phosphoproteins - answer-Involved in transduction Phosphoprotiens are target along STC - these change how Neurotransmitter is released phosphoproteins formed - answer-Helps to send message to
