ATP is an energy carrier that holds energy after processes like cellular respiration. The body can turn ATP into energy to do processes like physical movement later on.
Hope this helps :)

B)protons, down
Explanation:
Chemiosmosis is the diffusion of ions through a selective permeable membrane. It specifically refers to the production of ATP through the movement of hydrogen ions through an inner membrane during cellular respiration. Hydrogen ions diffuse from an area of high proton concentration to one of lower concentration.
