Question

The difference between respiration and combustion is related to respiration being
A. Multistep
B. Enzyme controlled
C. Intracellular
D. All the above

Answer 1

Hint: Respiration is the metabolic process where the certain organisms that obtain energy from the molecules. Combustion is the process of an act of burning. Here, we are going to see the difference between respiration and combustion and its relation. Through some of the information, it could be found and analyzed.

Complete answer:
Respiration is the biochemical process which occurs inside the living cells. In combustion, it is a physicochemical process that is non-cellular. Respiration is the slow process that releases the energy in a few steps and is stored as the adenosine triphosphate. In combustion, this is the fast process that releases energy in the increase in temperature. Respiration involves various kinds of enzymes whereas combustion involves no such enzymes. In the respiration process, the part of the energy liberated is heat. In combustion, more energy is liberated as the heat. Respiration takes place here at the normal temperature whereas combustion takes place at the high temperature. In respiration, oxygen takes place and is used as the oxidant in the last step of this process. In the process of combustion, oxygen is directly used in this process. So, the difference between the both of the process that includes respiration as well as the combustion is related to the multistep, it is enzyme controlled and as well as intracellular.

Hence, it is clear that the correct answer is Option D.

Note:
Here, respiration is the chemical reaction where the energy is released between oxygen and the glucose. This energy releases cells from the glucose. Then, in the combustion there is essential burning where the oxygen reacts with fuels and produces energy. Here, oxygen plays a vital role in both of the processes. These are some of the common points in the respiration and combustion.
