Aerobic respiration produces more usable chemical energy than fermentation because it involves __________.
Open in App
Solution
The correct option is C Partial oxidation of food
- Aerobic respiration is the process that leads to the complete oxidation of organic substances in the presence of oxygen and releases CO2, water, and a large amount of energy in the form of high energy bonds of ATP.
- In the cells of all living organisms, cellular respiration begins with glycolysis. In this process, glucose undergoes partial oxidation to form two molecules of pyruvic acid.
- In the absence of oxygen, pyruvic acid is converted to CO2 and ethanol by fermentation. In some organisms, lactic acid is formed from pyruvic acid, e.g., muscles during exercise.
- In fermentation, less than 7% of the energy is released from glucose molecules because it is not completely oxidized.
So, option C is correct.
