Where Do You Get Your Energy
Cells extract energy from sugar to produce ATP, the molecular fuel that powers all life processes. This interactive activity adapted from the Exploratorium delves into the processes that enable cells to unlock the energy contained in the foods we consume. We often use the term "energy" as an informal shorthand for our ability to stay alert and complete tasks. In fact, the presence of energy-rich molecules and our cells' ability to obtain, process, and use this energy is critical to life.
