RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a definition of respiration?
A
breathing
B
the release of energy from food
C
obtaining oxygen and releasing carbon dioxide
D
exchanging gases
Explanation: 

Detailed explanation-1: -The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.

Detailed explanation-2: -Respiration is the process through which living organisms take in oxygen and give out carbon dioxide to release energy. During respiration, there is a release of carbon-dioxide and water when glucose is broken down in the presence of oxygen. During this reaction, the energy is released.

Detailed explanation-3: -Respiration is the cellular process of releasing energy from food and storing it as ATP.

Detailed explanation-4: -Respiration is a metabolic process in which an organism’s living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic molecules.

Detailed explanation-5: -“Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”
