You have discovered a new drug that you believe will be a powerful memory stimulant. There is a large demand for this drug among undergraduate students but before you can market it, the FDA wants you to determine the nature of the drugs receptor. In the lab you isolate neurons to determine the receptor as an ion channel; that is specific for a single ion and it has a reversal potential of 97.6 mV. Using the ion concentrations and constants, determine what ion is being transmitted by your ion channel. Given: Na+out= 140mM Na+in=10mM K+out=3mM K+in=150mM Cl-out=135mM Cl-in 5mM Ca2+out= 1.0mM Ca2+in=0.002mM Temp=25Celsius R=8.314 J*mol^-1 K^-1 F=96,500 J*volt^-1 mol^-1 Use natural logs (ln) for all calculations. (Please work out in step wise fashion and explain. Thank You.)
