Question

What is the current through the channel
The potential difference across the ion channel is 70mv. What is the power dissipated in the channel The biochemistry that takes place inside cells depends on verious elements, such as sodium, potassium, and calcium, that are dissolved in water as ions. These ions enter cells through narrow pores in the cell membrane known as ion channels Each ion Channel, which is formed from a specialized protein molecule, is selective foe one type of ion. When an ion Channel opens in a cell wall, monovalent (charge e) ions flow through the channel at a rate

Explanation / Answer

I = Q*N/t = 1.6E-19*1E7=1.6E-12 A

P = IV = 70E-3*1.6E-12=1.12E-13 W
