Base Your Answers to the Questions on the Following Information

Base your answers to the questions on the following information:
For a particular cell, the concentration of sucrose is 10 mM on the inside of the cell and 0.5 mM on the outside, whereas the concentration of sodium ions (Na+) is 0.5 mM on the inside of the cell and 10 mM on the outside. The membrane potential is - 150 mV, and the temperature is 25°C.
Constants: R = 1.987 cal/mol degree; T = 25°C = 298 K; F = 23,062 cal/mole volt

B) - 1.774 kcal/mol
C) +3.459 kcal/mol
D) - 7.007 kcal/mol
E) +7.007 kcal/mol
