text: Yo, check it out, here's the scoop
  Mg-ATP particles, bovine heart mitochondria group
  They got F1, yeah, more than 95 percent
  With the inhibitor protein, IF1 represent
  
  We solubilized and purified this F1-IF1
  Now we wonderin', is it monomers or dimers, son?
  Size exclusion chromatography, electron microscopy
  Showed us most of it was a dimer, believe me
  
  Two F1-IF1, that's how they roll
  In this naturally occurring complex, it's the goal
  The concentration determines the form it takes
  Dimeric or monomeric, that's the stakes
  
  There's an equilibrium, a balance between the two
  F1-IF1, switching forms, something new
  So remember, in this game, it's all about the concentration
  Determinin' the state of F1-IF1, no hesitation
