Well, not quite.                           Actually, glycolysis
                                            needs 10 chemical
                    It's a little more  reactions to turn that
                       complicated...   one glucose molecule
                                             into two pyruvate

                                                   molecules.

                                               to create lactate,
                                                  one additional
                                                      reaction is
                                                     performed.

It looks                                Ta-da!

                      AHH!                  Yes, it is a long

                      Are you kidding
                    me? It looks like    ATP molecules are
