In biology, potential energy refers to the stored energy within a system that has the potential to do work. Potential energy can be stored in the chemical bonds of molecules. For instance, the energy stored in the bonds of glucose molecules is released during cellular respiration to produce ATP, the energy currency of cells. Which of the following is an example of the conversion of potential energy into kinetic energy?

Synthesis of ATP from glucose

ATP hydrolysis to drive muscle contraction

Digestion of protein in the stomach

Pumping ions across a cell membrane
