Question 3. Consider a cell suspended in a fluid containing a particular solute. If initially the concentration of this solute within the cell is less than that in the surrounding fluid then solute will flow into the cell through its permeable cell wall at a rate greater than at which solute will flow out of the cell, resulting in a net flow of solute into the cell. Conversely, if initially the concentration of solute within the cell is greater than that in the surrounding fluid, there will be a net flow of solute out of the cell. Fick's law states that if the surface area of the cell is assumed to remain constant then the rate at which the concentration of solute inside the cell increases or decreases is directly proportional to the difference in concentrations of the solute inside and outside the cell. If the concentration of solute within the cell is denoted by c = c(t) where t is the time, the concentration of the solute in the surrounding fluid is maintained at a constant value a, and the constant of proportionality is denoted by k, express Fick's law mathematically in the form of a Timplo difforontiol îolun thin omm

difference between channels and transporters is that O Only channels allow for the passage of solutes against their electrochemical gradient. OTransporters allow for a greater rate of transport across a membrane than channels do. O Only channels allow for the transport of ions. Transporters must undergo a conformational change upon binding to the solute.
