This webcast shows animations of ATP synthase structure and the mechanism for synthesizing ATP. Biology is incredibly cool. Too bad they didn’t have stuff like this when I was in school, instead biology was mainly about memorizing boring lists of stuff.
ATP (adenosine tri-phosphate) transports chemical energy within cells. When one of the phosphates is released by ATP energy is given off (and ATP becomes ADP (adenosine di-phosphate) + Pi (inorganic phosphate). And then the synthase structure can then turn it back into ATP to be used again.
