WebAug 11, 2016 · So to summarize, the resting membrane potential occurs because of the following things. First, neurons create a concentration gradient. Then the membranes … WebThe resting membrane potential (RMP) of skeletal muscle is mostly a result of the K+ concentration ratio across the sarcolemma membrane. This is because there are more K+ channels than Na+ channels, and all cell membranes are more permeable to K+ than to Na+. Skeletal muscle has a resting membrane potential of -90 mV and it is measured as a ... WebThe resting membrane potential is closer to EK than ENa because at rest: (a) Vm – ENa = 0 (b) gNa = 0 (c) gK >> gNa (d) gK = 0 11. You discover an ion channel that, when open, is permeable to all ions. This channel lacks: (a) gating (b) quaternary structure (c) selectivity how is shilajit made
