  • What, How, Why for Cell Communication


    Directions- Below is a list of questions that I have come up with for this particular unit.  Remember that this is not a checklist but questions that you need to be very familiar.  If you can’t answer these questions then applying the information will be difficult.


    Note: This set of what, how, why questions are for chapters 11, 48, and 49  (aka this does not include questions from your poster presentation). 


    1)   Are the three different levels of signaling?

    2)   Are the three stages of cell signaling?

    3)   Is the significance of intracellular receptors?

    4)   Are g-linked receptors? Tyrosine kinase receptors? Ligand-gated channels?

    5)   Is a kinase cascade reaction? Are the proteins associated in a kinase cascade reaction?

    6)   Are secondary messengers?  Examples?

    7)   Is the difference between an action potential and a resting membrane potential?

    8)   Is the purpose of myelin sheaths?

    9)   Are the steps that generate an action potential?

    10)                  Kinds of channels, when opened, can cause membrane polarization?  Depolarization?

    11)                  are the divisions of the nervous system?  Neuron?

    12)                  Is the difference between divisions of the nervous system?

    13)                  Is the sequence of events that lead to muscle contraction?

    14)                  Are the two ways that neurotransmitter signals are “turned off”?

    15)                  Is the sequence of events that causes epinephrine to be released?



    1)   does a signal binding to a receptor cause a response?

    2)   do the proteins in question 4 above work?

    3)   is it that certain cells respond to certain signals but others don’t?

    4)   can the opening of ion gated channels in a neuron cause hyperpolarization/depolarization?

    5)   is an action potential propagated down a neuron.

    6)   are sodium-potassium pumps involved in establishing the resting membrane potential of a neuron?



    1)   do action potentials move faster through a mylinated vs. unmylinated neuron?

    2)   Is it said that the parasympathetic and sympathetic divisions are antagonistic?

    3)   Is it important that signals can be turned off?

    4)   does a neurons resting membrane potential exist?

    5)   Is it said that secondary messengers amplify signals?
