ATP

ATP is a crucial energy molecule found in all living cells, produced by respiration and used in cellular processes. The human body contains about 250 grams of ATP, equivalent to the energy of a single AA battery. Despite this small amount, the body continuously produces and breaks down ATP, resulting in a daily turnover equivalent to a person's body weight.
