As you read this, a minuscule 5 grams of a high-energy molecule called adenosine triphosphate - ATP - is causing all kinds of reactions in order to give you the energy to sit at your computer. In total, 8 ounces of ATP is being recycled hundreds of times each day, so many times that a human can use their body weight - 200 pounds of ATP in my case – every 24 hours.
