Example:
Imagine trying to break down a big, tangled ball of yarn to knit a sweater. Just like unraveling the yarn to make it useful for knitting, the Krebs cycle breaks down pyruvic acid to release energy that the cell can use. In this analogy, the tangled ball of yarn represents pyruvic acid, the process of unraveling it is the Krebs cycle, and the resulting yarn ready for knitting is the energy released for the cell's activities.
