Is not true about ATP

ATP (adenosine triphosphate) is often mistakenly thought to be the primary energy source for all cellular processes, but it is actually a carrier of energy rather than the source itself. Additionally, some may believe that ATP can be stored in large quantities, when in reality, cells maintain only a small pool of ATP that is rapidly regenerated. Lastly, while ATP is crucial for muscle contraction, it is not the only molecule involved in energy transfer within cells.
