The Golgi functions to…

Ion Intracellular Concentration (mM) Extracellular Concentration (mM) Permeability Sodium 8 145 0.04 Potassium 150 15 1.0 Chlorine 10 90 0.5 Refer to the table above.  1) Determine the membrane potential using the ions listed in the chart above.  However, this person is under the effects of the toxin from sea anemones.  This anemone toxin targets voltage gated potassium channels.  Take this into consideration when setting up your equation. 2) If the threshold for this cell is -55mV, would this cell reach action potential?  Yes or no.

Transgenic mice functions to help scientists do which of the following:

Refer to the image above. The PURPLE portion of the image refers to…

Ion Intracellular concentration (mM) Extracellular concentration (mM) Permeability Sodium 10 155 0.05 Potassium 140 5 1.0 Calcium 0.002 20 0.001 Chlorine 10 95 0.45 Use the table above.  1) Determine the equilibrium potential for sodium.  Round to the nearest whole number. 2) If the threshold is -55mV, will this cell reach action potential?

In order for an axon to maintain its connection with its target, the neuron must maintain its shape. What cytoskeletal proteins allow this to happen?

    Refer to the picture above. What structure is indicated by the end of the BLACK pointer at the left of the image?
