distingu between inspiration and combustion
Answers
RESPIRATION
Respiration is an Energy releasing process in which the glucose is oxidized with the help of oxygen and the breakdown of glucose releases the energy. In animals there are special organs for respiration, in plants gaseous exchange occurs by diffusion method.
COMBUSTION
Combustion is the process of burning something to get energy. During combustion, the heat is supplied on to Sugar the sugar first chars and then gives the flame. The sugar releases energy in the form of heat at a time. From this we can define combustion as a process of Burning the sugar to get energy.
Answer:
Respiration. Combustion
Respiration is a cellular
process Combustion does not occur inside the living cell
Respiration is a controlled biological process Combustion is an uncontrolled process
Energy is released in a stepwise manner with different biochemical reactions Energy is released in a single step
Less than half of energy is liberated as heat Energy is released as heat. It can get hot enough to produce incandescent light.
Temperature is not allowed to rise and controlled otherwise it can damage the cell The temperature during combustion is very high.
Adenosine triphosphate is formed during this process. On breakage of the molecular bond, energy is released for physiological processes. Adenosine triphosphate is not formed.
Oxidation occurs at the end of the reaction between oxygen and reduced coenzymes in the electron transport chain Substrates are directly oxidised in the combustion process
Enzymes are required for the process of respiration Enzymes are not required for combustion as it is a non-cellular process
Example: Aerobic respiration Example: Combustion of oxygen and hydrogen into water vapour
