What is/are effect on the membrane when extracellular concentration of K+ decreased?: (A) | magnitude of RMP, (B) | negativity of the membrane, (C) | magnitude of RMP, (D) | negativity of membrane
Answer is B. While K+ is positively charged and more abundant on the inside, there exists a great amount of negatively charged paicles (the anions), accounting for the negative charge inside the membrane. The cell membraneforms the border of a neuron and acts to control the movement of substances into and out of the cell. Ref guyton and hall textbook of medical physiology 12/e pg 58
