|
How does the amount of energy resulting from fermentation compare with that of aerobic respiration?
|
|
Aerobic respiration results in less energy.
|
|
|
Each process results in equal amounts of energy.
|
|
|
Aerobic respiration results in more energy.
|
|
|
Each process results in variable amounts of energy.

Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Comparing Fermentation and Cellular Respiration Because fermentation doesn’t use oxygen, the sugar molecule doesn’t break down completely and so releases less energy. The fermentation process in cells releases about two energy units whereas cellular respiration releases a total of about 38 energy units.
