When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
Answer: Protiens help provide structural support for our metabolism, and they can act as enzymes, carriers, or hormones to help us. They provide growth and maintenence and also act as messengers for our brain. They bolster our immune system and also transport/store nutrients. Basically, they do a whole lot!
