A single ion channel is selectively permeable to K+ and has a resistance of 1.0 GΩ. During an experiment the channel is open for approximately 1.1 ms while the voltage across the channel is maintained at +72 mV with a patch clamp. How many K+ ions travel through the channel?
Homework Answers
As V= IR. I = 72mV/1Gohm. Hence current flow is 7.2×10^-8 A.
Charge flown = current×time. Hence total charge flown is 7.92×10^-11 C.
Each K+ ion contain 1 proton. Hence you can calculate number of K+ ions flown.
Ans is 4.94×10^8.

IMAGE K shows single-channel recordings from an ionotropic
receptor, that were made using the cell-attached patch-clamp
configuration. All ion concentrations are as with normal neurons,
and ENa = +60 mV, EK = -80 mV, and ECl = -70 mV. In these traces,
the membrane potential is being held at -60 mV. In the top trace,
the experimenter stimulated the presynaptic neuron with no drug
present, and in the bottom trace they had applied a drug.
