Verified Answers Graded A+
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 phosphoprotiens

, second 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 gene

One of the end targets along with the gene

Works on ion conduction



transcription factors? - Answer: Converting DNA into RNA



transcription factors final target - Answer: gene expression



neuronal gene expression - Answer: environmental factors can affect gene expression -
(important things to take away)



Epigenetics - Answer: can turn gene on or off by modifying cromatin in cell nucleus
