A certain single ion channel is selectively permeable to K+ and has a resistance of 1.15 GΩ , therefore a current of potassium ions through the channel is possible. During an experiment, the channel is open for approximately 1.50 ms while the voltage across the channel is maintained at 81.5 mV . How many K+ ions travel through the channel during this
A certain single ion channel is selectively permeable to K and has a resistance of 1.15 GΩ. During an experiment, the channel is open for approximately 1.50 ms while the voltage across the channel is maintained at 81.5 mV with a patch clamp. How many K ions travel through the channel during this time?
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?

Please help and show work. I keep getting the wrong answers for these problems 1. Cell membranes contain channels that allow Na + ions to rush in. Consider a channel that has a diameter of 2.91 nm and a length of 13.5 nm. If the channel has a resistance of 18.5 GΩ, what is the resistivity ? of the solution in the channel? 2. What is the resistance of a 54.154.1-m-long aluminum wire that has a diameter of 8.79 mm8.79...
15. Estimate the resistance ? of a standard (not a high-speed) phone charging cable. ?=_____Ω 19. A certain single ion channel is selectively permeable to K+ and has a resistance of 1.15 GΩ , therefore a current of potassium ions through the channel is possible. During an experiment, the channel is open for approximately 1.50 ms while the voltage across the channel is maintained at 89.5 mV . How many K+ ions travel through the channel during this time? number...
When potassium ions (K+) cross a membrane through an ion channel, they acquire a velocity on the order of 10-2 m/s. Approximately what are the minimum and maximum values of the magnetic force on a K+ due to Earth’s magnetic field?
Under certain circumstances, potassium ions ( K+ ) in a cell will move across the cell membrane from the inside to the outside. The potential inside the cell is −85.5 mV and the potential outside the cell is zero. What is the change in the electrical potential energy of a single potassium ion as it moves across the membrane? change in potential energy: J Does the potential energy of the potassium ions increase, decrease, or remain the same as the...
