Question

Differentiate between Respiration and Combustion

Solution

  Respiration Combustion
1 It occurs inside living cells It is a noncellular process.
2 Respiration is biochemical process. Combustion is  physio-chemical process
3 Most of the energy is trapped in ATP molecules ATP is not formed
4 Oxidation occur at the end of reaction(terminal oxidation) between reduced coenzymes and oxygen The substrate is directly oxidised in combustion
5 Energy is released in stages as chemical bonds are broken in steps Energy is released in a single step as all chemical steps occurs simultaneously
6 A number of intermediates are formed. They are used in the synthesis of different organic compounds No intermediates are produced in combustion
7 A number of enzymes are required., one for each step or  reaction. Burning is a non-enzymatic process
8 Less than 50% energy is liberated in the form of heat energy. Light is rarely produced. Energy is libreated in the form of both light abd heat energy
9 Temperature is not allowed to rise Temperature become very high
  Is there an error in this question or solution?
