Question

The biochemistry that takes place inside cells depends on various 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 for one type of ion. When an ion channel opens in a cell wall, monovalent (charge ) ions flow through the channel at a rate of 1.0*10^7 ions Question 1: what is A ? I = ____ A 2: what is P? P = ____ W

Explanation / Answer

I think for the second question,current density(J) = I/A

Thus, you would take the 1.8 pA / the area of the channel

The area of the channel is pi*(0.30 nm)^2

Thus, I beleive you would get 1.9 x 10^-6 A/m^2
