The Respiration Framework addresses cellular respiration at the organismal, cellular, and subcellular levels, more specifically glycolysis, pyruvate oxidation, Kreb cycle, oxidative phsophorylation, electron transport chain, and digestion are included.  The role of respiration in food chains is also addressed.  The explanations of these processes are organized around three practices:

  • tracing matter
  • tracing energy
  • keeping track of location and scale
