Our cells create and store energy by making a chemical gradient of protons, and then allowing them to flow from high concentration to low concentration. This process is part of the cellular respiration, specifically in the electron transport chain stage, where the energy from electrons is used to pump protons across a membrane, creating a gradient. When these protons flow back across the membrane, from high concentration to low concentration, they pass through a protein called ATP synthase, which uses the energy from this flow to synthesize ATP, the main energy currency of the cell.
