प्रश्न
How will you demonstrate that energy is released during aerobic and anaerobic respiration?
उत्तर
Take two thermos flasks. In the first flask, keep some germinated seeds and a little water to keep them moist. In the second flask, keep some boiled seeds. Place corks fitted with thermometers on both the flasks. Keep the flasks airtight. Note the temperature in both the thermometers. Leave the flasks for sometime and again record the temperature. It is observed that the temperature of the first set increases and in the second case, it is not affected. The rise in temperature is because, during respiration, germinated seeds release some energy in the form of heat energy.
