How are combustion and cellular respiration different?

Difference Between Respiration and Combustion

Respiration Combustion
It takes place in a controlled manner inside the cells. It is an uncontrollable process.
Heat is produced in the cellular respiration. Example, the rate of respiration increases when we exercise and we feel warmer. It produces energy as waste and heat.

How does cellular respiration compare to the combustion of a candle?

Cellular respiration can be compared to burning candles. Like candles, cells need fuel and oxygen in order to burn, and they produce carbon dioxide and water as they release the energy from the chemical bonds of the fuel.

How are combustion and cellular respiration similar to each other Class 7?

Combustion and cellular respiration are similar to each other because at the end of both processes heat and energy are released. It is a fast process. It is a single-step process, and energy is released in the form of heat and light. It is a multi-step process, and energy is stored in the form of ATP.

What is the major similarity between respiration and combustion?

Both Respiration and Burning uses oxygen. Both Respiration and Burning produces energy. Both Respiration and Burning gives out carbon dioxide as the end product. The overall chemical reactions of both Respiration and Burning are the same.

Can cellular respiration be called combustion?

Answer: Cellular respiration is considered an exothermic redox reaction which releases heat. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow release of energy from the series of reactions.

Why is respiration considered as a combustion process?

Cellular respiration is an example of slow combustion. In respiration, glucose is oxidised and carbon dioxide and energy are released in the process. This is a very similar reaction to combustion. Slow combustion is a form of combustion which takes place at low temperatures.

Which combustion is cellular respiration?

Cellular respiration resembles ordinary combustion or burning in the breakdown of chemical bonds, use of oxygen, production of carbon dioxide, and release of energy, but there are some fundamental differences between the two processes.

How are combustion and cellular respiration similar to each other in what ways are they different class 7?

Both combustion and cellular respiration involve the oxidation of substances. While in respiration, food is oxidised and energy is released in a stepwise manner, in combustion the combustible substance is oxidised with the release of large amount of energy. Also, in both the processes energy is liberated.

Can cellular respiration be called combustion explain?

Cellular Respiration is the release of energy from food through oxygen. Cellular Combustion is the burning of a substance which releases oxygen and carbon compounds. Cellular Combustion takes place at much higher temperatures than Cellular Respiration because the energy released takes the form of heat.

Why is cellular respiration not combustion?

The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

Why is cellular respiration considered a combustion reaction?

In respiration, glucose is oxidised and carbon dioxide and energy are released in the process. This is a very similar reaction to combustion. Slow combustion is a form of combustion which takes place at low temperatures. Cellular respiration is an example of slow combustion.

What are the 3 processes that make up cellular respiration?

All About Cellular Respiration. The three processes of ATP production or celluar respiration include glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation.

What are the 7 steps of cellular respiration?

The steps of aerobic cellular respiration are: Glycolysis (the break down of glucose) Link reaction Krebs cycle Electron transport chain, or ETC

What are the 5 steps of respiration?

A hand-drawn tour through the five steps in the physiology of respiration: ventilation, external respiration, transport, internal respiration, and cellular respiration are each covered.

How is respiration similar to combustion reaction?

Cellular respiration is similar to combustion because both reactions rely on fuel (reducing and oxidizing agents) to start the reaction; the difference is that in cellular respiration, enzymes are used during the reaction. Both result in smoke (CO2 and H20) and energy.
