Cycling of nutrients and flow of energy
It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
They might still be under the influence of medication given to them during the surgery. no one under the influence should drive. it is a safety hazard for them to drive

Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
