Why can respiration be called a controlled energy-releasing chemical process?
Answer and explanation
Correct answer: Oxidation of glucose releases energy in a controlled way
Respiration is a chemical process in which glucose is gradually oxidised, ultimately producing carbon dioxide and water and releasing energy. The energy is transferred in several controlled steps and captured partly in ATP, rather than being released suddenly as heat in one uncontrolled event. Therefore A is correct. Respiration does release energy and is not merely a change of state or a precipitation process.
