Hey there,
These are two review sheets that pertain to some of the material we learned so far in class. There are a couple parts you will not need to know for quiz 1. You will not need to know the "types of synapses" from the 1st review sheet (axodendritic, axosomatic, etc... These will be covered in later chapters). You will also not need to know about synaptic vesicles/secretory granules from the 2nd review sheet.
Regarding the Nernst Equation, here is a sample problem. I assume they will be much easier since Professor Patrick assumes you will not need a calculator. If you can do this, then you should have no problem.
1. Use the Nernst equation to calculate the equilibrium membrane potential for potassium (K+) ions if the concentration outside the cell is 20mM and the concentration inside the cell is 300mM.
Ek = 61.54mV log ([k+]o / [k+]i)
Ek = 61.54mV log ([20]o / [300]i)
log (1/15) = -1.17
(If you are having trouble with logs, do a quick review: http://en.wikipedia.org/wiki/Logarithm)
Ek = 61.54mV (-1.17)
Ek = -72.00mV
If you have any questions, please email me.
