# Free Energy for Transport of Cl- Using Membrane Potential

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

Blood contains 0.1 M Cl-. Brain tissue contains about 0.02 M Cl-.
Calculate:
(1) the G for the transport of Cl- from blood into brain cells
(2) the energy expended by brain cells in transporting Cl- outward against the concentration gradient. Assume a membrane potential of -75mV (inside).
