Объяснение

Respiration breaks sugar down using the gas the plant takes in, and it leaves behind the gas that living things breathe out together with water; energy is released as this happens, but energy is not a substance and so has no place among the names. Turning the arrow round instead describes the reaction that builds the sugar rather than the one that breaks it down.
