Light is the most precise way to heal ✨ ATP, or adenosine triphosphate, is necessary for energy because it is the primary molecule used by cells to store and transfer energy within the body. When ATP is broken down into adenosine diphosphate (ADP) and inorganic phosphate, energy is released and can be used by the cell to fuel various biological processes. This process is essential for powering cellular activities such as muscle contraction, nerve signaling, and metabolism. Without ATP, cells wou
