How are combustion and cellular respirations similar to each other? In what way are they different ?
Answers
Similarities – During cellular respiration the sugar molecules in food are form carbon dioxide and water and energy is given out.
C6 H12 O6+ 602 → 6CO2 + 6H2O + energy
This is similar to the chemical reaction that occurs during burning or combustion.
ParameterCombustionCellular Respiration
RateCombustion is a fast process.Cellular Respiration is a slow process.
TemperatureIt occurs at high temperature.It occurs at body temperature.
PlaceIt can occur anywhere.It occurs only in living cells.
Energy is released in a single step in the form of heat and light.Energy is released in steps and stored in chemical molecules called ATP.
Answer:
combustion and cellular respiration involves the oxidation of substances. While in the respiration food is oxidized and energy is released in a stepwise manner, in combustion the cumbustible substance is oxidized with the release of large amount of energy. in the both processes energy liberted.
