Fermentation, respiration and photosynthesis are the main ways. Cells use ADP (Adenosine di-phosphate) and add a phosphate group. After ATP is broken down into ADP and a phosphate group, the parts recycle to form ATP again. The ongoing process of breaking and rejoining phosphate groups is what keeps the cell going. Transport ATP used in transport is primarily used to pump substances into the cell. The energy release from the ATP allows the substance to go against its concentration gradient. Generating Charges Mechanical Cells use ATP for many mechanical purposes. The ATP's energy is converted into kinetic energy.
