Answer:
ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy. ATP is the immediately available source of energy for almost all bodily functions, including muscle contraction. It is formed when a phosphate group is added to ADP during phosphorylation, a process that requires a considerable amount of energy. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen. What are the 3 steps to energy exchange from ADP to ATP?

What exactly is an ATP?
All living species' cells include the energy-transporting chemical adenosine triphosphate (ATP). The chemical energy generated by the breakdown of food molecules is captured by ATP and released to power other cellular functions.
Cells need chemical energy to do three broad types of tasks:
- to drive metabolic events that would not happen naturally;
- to transport necessary molecules across membranes;
- to perform mechanical labor, such as moving muscles.
- Energy is transformed from storage molecules into ATP when the cell needs it.
- Then, ATP acts as a shuttle, transporting energy to regions of the cell where energetically demanding processes are occurring.
How does ATP become energy?
- Energy is released and ATP is changed into adenosine diphosphate (ADP) when one phosphate group is removed by breaking a phosphoanhydride bond during a procedure known as hydrolysis.
- As with the removal of a phosphate from ADP to create adenosine monophosphate (AMP), energy is likewise released.
How exactly does ATP get produced?
- Although ATP is constantly broken down by cells to provide energy, it is also constantly produced from ADP and phosphate by the processes of cellular respiration.
- ADP and phosphate are converted to ATP by the enzyme ATP synthase, which produces the majority of the ATP in cells.
