13) If a positively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be directed ________. Thus, the equilibrium potential for this ion would be ________ charged.BDiff: 7 Page Ref: 9914) Which of the following cells would have a greater electrical attraction for sodium ions to enter the cell?A) cell with membrane potential = -70 mVB) cell with membrane potential = -90 mVC) cell with membrane potential = -50 mVD) cell with membrane potential = 0 mVE) cell with membrane potential = +20 mVAnswer: BDiff: 4 Page Ref: 9815) If a negatively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be directed ________. Thus, the equilibrium potential for this ion would be ________ charged.ADiff: 7 Page Ref: 9916) If a negatively charged ion is more concentrated inside the cell, the forces required to balancethe chemical gradient would be directed ________. Thus, the equilibrium potential for this ion would be ________ charged.CDiff: 7 Page Ref: 994
