- Cellular respiration is a chemical change.
- Cellular respiration is an example of conservation of energy.
- Cellular respiration is a change of the state of matter.
Answer: Option 2, 3 & 4
Step-by-step explanation:
The process in which an organism uses Oxygen and expels carbon dioxide is called as cellular respiration. Energy is released due to cellular respiration when it acts with the food molecule eliminating the waste products. Cellular respiration hence undergoes a chemical change.
During the process energy is conserved so as to be utilized during requirement. A change in the state of matter also occurs during this process. When the sugar reacts with the Oxygen molecule the end product formed is water and carbon dioxide.
