Question

Aerobic respiration produces more usable chemical energy than fermentation because fermentation involves:

• A. Formation of lactic acid
• B. Complete oxidation of food
• C. Partial oxidation of food
• D. Evolution of $\text{C}{\text{O}}_2$ and alcohol

Answer 1

The correct option is C Partial oxidation of food

Aerobic respiration produces more usable chemical energy in the form of ATPs than fermentation because aerobic respiration involves the complete oxidation of glucose and the release of carbon dioxide and water as end products. On the other hand fermentation, a type of anaerobic respiration seen in organisms like yeast, involves the partial oxidation of glucose and release of ethanol and carbon dioxide as the end products. Due to the complete oxidation of glucose, ATP formed during aerobic respiration is much more than anaerobic respiration.
