Respiration Is A Reaction That Breaks                              Organisms like us break
Down Glucose To Create Energy                                    down starch into glucose,
                                                                  which is used to make ATP,
               Saccharides that are created by                   with the assistance of the
                plants through photosynthesis                    oxygen that we breathe in.

                     are stored in the form of                   Glucose
                   starch, which we animals eat.
                                                                                 Energy
                                                          MmM,
                                                          yummy

                                                                 That's internal respiration!

  Here, take a look at this.

It's the general formula
        for respiration.

Glucose Oxygen                              Water                Carbon   Water  Energy
                                                                 dioxide

     Oh, that makes
   it crystal clear!
Glucose and oxygen
  are consumed, and
    carbon dioxide,
  water, and energy

      are produced.

Now, let's take a closer                                        And here they are!
  look at this reaction.
                                                                      Glycolysis
                            You can think                         Citric acid cycle*
                           of respiration
                          as having three                                 Electron
                                                                    transport chain
                                 stages...
                                            * This is also called the Krebs cycle or the TCA cycle.
