Energy currency

Energy currency refers to the way living organisms store and transfer energy for biological processes. Think of it as a rechargeable battery within cells. The most common form in biology is a molecule called ATP (adenosine triphosphate), which captures energy from food and releases it when needed to power activities like muscle movement, growth, and repair. ATP acts as a universal energy "money" that cells exchange to perform various functions efficiently. This system ensures energy is readily available and used effectively, maintaining the organism's overall health and activity.
