input: The following are multiple choice questions (with answers) about medical knowledge.   **Question:** Cell membrane of a cell is freely permeable to three ions X, Y and Z. At resting membrane potential, the respective equilibrium potentials of Xand Y are -30mV and -40 mV.What will happen to the membrane potential if a drug is infused which can block the permeability of Z?   (A) Depolarisation   (B) Hyperpolarization   (C) No change   (D) Hyperpolarization following repolarization
