Potential energy is energy stored in a object , due to object itself or it's position.
The example of potential energy is water stored in reservoir due to its position.the potential energy can convert into kinetic energy by moving water in tunnels. or big pipelines and used to move turbines.
So example of potential energy is water stored in the reservoir

Oxidative phosphorylation is achieved through chemiosmotic coupling, which turns chemical energy into osmotic potential energy that is used to synthesize the energy “currency” of the cell (ATP). This process is divided into stage 1 (electron transport chain) and stage 2 (ATP synthase). Answer the following questions about each stage: In stage 1, what is the energy source used to form the proton gradient across the inner membrane and what is the principal carrier of this energy source? In stage 2,...
