WebJun 14, 2024 · Because the movement of ions and other substances within the cell is slow compared to the rate at which a wire can transfer electrons from one terminal to another, potential differences that develop within an operating cell decrease the electrical potential across the terminals.

WebSmall substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. WebIt is electrical. It is chemical. B. Identify the characteristics that play a role in the electrical signals created by nervous tissue. Select all that apply. Specific channels alter membrane permeability to ions. Semipermeable membranes help create a separation of ions. Electrical charges are separated across the cell membrane.
