Energy is needed to transport a substance from outside a living cell to inside a living cell. The energy is measured in kilocalories per gram molecule and is given by: E=1.4(logC1-logC2), where C1 represents the concentration of the substance outside the call and C2 represents the concentration of the substance inside the cell. a) rewrite the formula as a single logarithm. b) find the energy needed to transport the exterior substance into the cell if the concentration of the substance outside the cell is double the concentration inside the cell. c) what is the sign of E if C1
