Respiration Respiration  – is the process by which cells obtain energy from glucose  During respiration, cells break down simple food molecules such as  sugar and release the energy they contain During photosynthesis, plants capture energy from sunlight and “save”  When your cells need energy, they breakdown the carbohydrates  The Two Stages of Respiration:  1    st     Stage      –  takes place in the cytoplasm of the organelle’s cells molecules of glucose are broken down into smaller molecules **Oxygen is NOT involved!!!** 2    nd     Stage      –  takes place in the mitochondria the molecules are broken down into even smaller molecules –  these chemical reactions require oxygen **Mitochondria are sometimes called the “powerhouse” of the cell  because they release a great deal of energy in stage 2!!**
