Concept explainers
Concentration of a solute According to the Fick’s law, the diffusion of a solute across a cell membrane is given by
Where A is the area of the cell membrane, V is the volume of the cell, c(t) is the concentration inside the cell at time t, C is the concentration outside the cell, and k is constant. If co represents the concentration of the solute inside the cell when t = 0, then it can be shown that
a. Use the last result to find
b. Substitute back into Equation (1) to show that (2) is indeed the correct antiderivative of (1).
