Respiration in Organisms - Chapter Wise CBSE Solved Question and Answer Based On NCERT
Points To Remember:
- Respiration releases energy from food
- The oxygen that we inhale breaks down glucose into carbon dioxide and water. This releases the energy
- Aerobic respiration uses oxygen to breakdown the food. Anaerobic respiration does not use oxygen
- Breathing is a process of respiration during which oxygen is inhaled and carbon-dioxide is exhaled
- Humans and animals use lung as the respiratory organ. Earthworm breathes through its skin and fish uses its gills
- Respiration can be measured using a device called a respirometer
- Increases physical activity enhances the rate of breathing
- In animals like cow, dog and cat the process of breathing and respiratory organs are similar to those in humans
