A membrane separates two solutions of glucose. The outside concentration of 5 mM and the inside has a concentration of 20 mM. Consider that there is an efflux of 1 pmol of glucose to the outside of the cell. How much energy does the transport of 1 pmol of glucose involve? R = 8.314 joule mol-1 oK-1 , T = 37oC
B. Is the free energy change positive or negative (prove it).
