Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that at a certain ratio of [A]_inside to [A]_outside the Delta G for the transport of substance A from outside the cell to the inside, A_outside rightarrow A_inside, is – 11.3 kj/mol at 25 degree C. What is the ratio of the concentration of substance A inside the cell to the concentration outside? [A]_inside/[A]_outside = __
