Essay

We have finally discovered life on Venus.NASA scientists are investigating a newly discovered life form: a single-celled organism found in the swampy canals.You have been contracted by NASA to perform an electrophysiology study.Using intracellular electrodes to measure the electrical charge inside the cell,you find it has a resting membrane potential of -45 mV when the outside fluid is arbitrarily set to 0 mV.Additionally,you have determined ion concentrations and listed them below.
For fun,you have used new molecular biology techniques to insert protein channels into the cell membrane that allow only Na⁺ and Cl^- to pass.Predict which ion(s)will move.Tell what direction it (they)will move and what force(s)is/are acting on it (them).
