How does the synthesis of ATP occur? When one of these phosphates is removed, the energy that keeps human beings alive is produced. Why must ATP be continuously made within the mitochondria of cells that need it? (be specific), ATP-Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus. Whenever energy is required for any metabolic reactions or other cellular activities, ATP is converted into ADP releasing energy. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. Adenosine diphosphate and adenosine triphosphate are organic molecules, known as nucleotides, found in all plant and animal cells. They can convert harvested sunlight into chemical energy (including ATP) to then drive the synthesis of carbohydrates from carbon dioxide and water. The equation for the reaction is ATP --> ADP + P, where P is the third phosphate group. 144 editable illustrations format. Substrate-level phosphorylation occurs in the cytoplasm when an enzyme attaches a third phosphate to the ADP (both ADP and the phosphates are the substrates on which the enzyme acts). Determine if each of the following is used or produced during photosynthesis. ADP has two phosphate groups, and when an additional phosphate group is added, it becomes ATP.
