    • The net loss of positive ions is for every two potassium ions pumped inside the cells, there are three sodium ions pumped outside the cell in each cycle, thus, 5 cycles is equals to 15 positive ions outside the cells and 10 positive ions inside the cells with a difference of When there is more potassium than sodium positive inside the cells, and more sodium than potassium ions outside the cells, the resting membrane potential of a neuron is mv that means the inside of the. c. mv. Would you expect the Model 1 system to change over time? Which molecules are able to pass through the semi-permeable membrane? No. The triangles will remain on the left side because they are too big to pass through membrane.
