Step 1: Understand that protons are positively charged particles found in atoms.
Step 2: Learn that the inner mitochondrial membrane is a barrier inside the mitochondria, which are the energy factories of cells.
Step 3: Know that a gradient means there is a difference in concentration; in this case, there are more protons on one side of the membrane than the other.
Step 4: Realize that this difference in proton concentration creates potential energy, similar to water behind a dam.
Step 5: Understand that this energy can be used to make ATP, which is the energy currency of the cell.
Step 6: Conclude that the proton motive force is the energy created by the difference in proton concentration across the inner mitochondrial membrane that helps produce ATP.
