Select all of the accurate statements ⚠️This is multiple choice⚠️

(1) Cellular respiration is a physical change.

(2) Cellular respiration is a chemical change.

(3) Cellular respiration is an example of conservation of energy.

(4) Cellular respiration is a change of the state of matter.

(5) Cellular respiration is an example of conservation of mass.

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

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.

(4) Cellular respiration is a change of the state of matter.

Explanation:

The food molecule is being degraded into its small units to produce energy. Therefore, mass is converted in energy.
