Questions and CORRECT Answers
The Nernst equation predicts that - CORRECT ANSWER - as extracellular potassium
increases, RMP decreases
For a Pearson correlation, you should report these values - CORRECT ANSWER - p,r,n
Which is the correct order of events for blue light-induced EPSP's in muscle 6 of a ChR: -
CORRECT ANSWER - ChRs expressed in the glutamate neurons open sodium flows into
those glutamate neurons, calcium enters those glutamate neurons, glutamate is released into the
synapse, glutamate binds to AMPA receptors expressed in muscle 6, sodium enters the muscle
cell.
