1.	Respiration is viewed most simply as the oxidative production of ATP. Justify the statement.
Answer» The energy-releasing process by oxidation of organic food materials in the living cell is respiration. During this process, the energy contained in the food is released and is trapped in the ATP molecules. NADH⁺H⁺ and FADH₂ formed during various steps of respiration are oxidised, and protons (H⁺) and electrons (e ) are released. These electrons are transported to the oxygen through a series of electron carries in the electron transport system (ETS), and their energy is stored in ATP molecules. So, respiration is process of oxidative production of ATP. 45% of energy released during the oxidation of 1 glucose molecule is stored in 38 ATP molecules.
