What is released when glucose breaks down during respiration?
Answer and explanation
Correct answer: Energy
During respiration, glucose breaks down and releases the chemical energy stored in it. Cells use this energy for their activities, so energy is the correct answer. Oxygen is generally used as a reactant in aerobic respiration; it is not released as energy. Exam tip: Remember respiration as an energy-releasing (exothermic) process.
