A metabolic process which results chemical changes in organic substrates by the action of enzymes is known as fermentation. It is also defined as the energy is extracted from the carbohydrates in the absence of oxygen. In this process, glucose breaks down in the absence of oxygen.
Answer to Problem 88A
Total energy converted to ATP during cellular respiration = 1159 kJ
Total energy converted to ATP during fermentation = 61 kJ
Energy converted to ATP during cellular respiration is more than energy converted to ATP during fermentation.
Explanation of Solution
In cellular respiration process, 1 mole of glucose results in the formation of 38 moles of ATP.
In fermentation process, 1 mole of glucose results in the formation of 2 moles of ATP.
Since, one mole of ATP = 30.5 kJ energy
Total energy in kJ which is converted to ATP during cellular respiration is calculated as:
Energy converted to ATP =
=
Total energy in kJ which is converted to ATP during fermentation is calculated as:
Energy converted to ATP =
=
According to the above calculations, the energy converted into ATP during the process of cellular respiration is more than the energy converted into ATP during the process fermentation.
