Distinguishing Respiration and Combustion
The main difference between respiration and combustion is that respiration is the process of extracting energy from organic molecules, while combustion is the process of extracting energy from inorganic molecules. Combustion is a type of respiration, but not all respiration is combustion.
Respiration is the process of breaking down glucose into adenosine triphosphate (ATP) and carbon dioxide. This process requires oxygen, which is why respiration is often called “oxidation.” The ATP is then used to power the cell’s activities.
Combustion is the process of breaking down a fuel, such as coal or gasoline, into energy. This process also requires oxygen, and it produces carbon dioxide and water vapor. The energy from combustion can be used to power machines or to heat buildings.
What is Respiration?
Respiration is the process by which an organism takes in oxygen from the environment and uses it to produce energy. The energy is used to power the organism’s cells and allow them to carry out their functions.
What is Combustion?
Combustion is the combination of a fuel and oxygen to create heat and light. When a fuel is burned, it reacts with oxygen to create heat, water vapor, and carbon dioxide. The heat from the combustion process is used to produce energy, such as in a furnace or an engine.
Difference Between Respiration and Combustion
The processes of respiration and combustion are both energy-yielding processes, but they are different in a number of ways.
The primary difference between respiration and combustion is that respiration occurs in the presence of oxygen, while combustion occurs in the absence of oxygen. In respiration, glucose is converted into adenosine triphosphate (ATP), which is then used by the cells to carry out their functions. In combustion, glucose is converted into carbon dioxide and water.
Another difference between respiration and combustion is that the products of combustion are harmful to the body, while the products of respiration are not. The carbon dioxide and water produced by combustion are harmful because they cause acidification of the blood and tissues. The ATP produced by respiration is not harmful to the body.
Finally, the rate of respiration is much slower than the rate of combustion. Respiration occurs at a rate of about 0.5 liters per minute, while combustion occurs at a rate of about 100 liters per minute.

The aim of this experiment was to investigate the effect of caffeine on the heart rate of rats.
The heart rate of rats was monitored before and after they were given caffeine. It was found that the heart rate of rats increased after they were given caffeine. This suggests that caffeine has a stimulant effect on the heart rate.
Similarities Between Respiration and Combustion
Respiration and combustion are both processes that involve the transfer of energy from one molecule to another. In both cases, energy is released in the form of heat. In respiration, this energy is used to power the cell’s metabolic processes. In combustion, it is used to produce heat, light, and motion.
