A Draw graphs showing the effect on action potentials in a cell following effective doses of each of the listed neurotoxins. Assume that the cell is normally brought to threshold by an electrical stimulus applied to it, so that any abnormality is due to the toxin. Precise values for voltage and duration are not important, just a general trend in how the action potential may be different from normal 1. puffer fish poison (blocks voltage-gated sodium channel activation) (25 Points)...

5. Draw a graph showing what would happen to resting membrane potential over time, if the sodium/potassium pump were not functioning. How would this affect a neuron's ability to produce action potentials? What does this imply about the quantity of ions that normally cross the membrane during the course of an action potential? (Group D). Topic 2: Action potential conduction and synaptic transmission 6. How would you alter sodium and/or potassium...

1. For each of the statements below relating to action potentials, fill in the blank with the correct ion: Ca++, K+, Nat, or Cl-. (5 points) At resting potential, the equilibrium voltage is maintained in part by chloride ions and other anions inside the cell and by the action of the the pump, there is a higher concentration of concentration of pump. Because of the action...

Cell # 1 forms an excitatory synapse onto cell # 2 , when cell #1 fires a single action potential it releases glutamate onto the membrane of cell #2 resulting in a 5 millivolt depolarization, a 5 mV excitatory postsynaptic potential, when cell #1 fires three action potentials in rapid succession this causes a 15 mV depolarization in cell #2 resulting in cell #2 reaching threshold and firing its own action potential. Cell #1 Cell #2 +40 Vm IN Cell...

m2 6 Fig awre . 2. The magnitude of the force of attraction between the positively charged proton and the negatively charged electron in a Hydrogen aton is given by f(r) = ke2/r2 where e is the charge on the proton, k is Coulomb's constant, and r is the distance between the proton and the electron. Assume that the protorn can't move. The...
