Explanation:
Detailed explanation-1: -Thus a total of 2 ATPs are generated from the fermentation of a glucose molecule.
Detailed explanation-2: -Fermentation involves the step of glycolysis in respiration, but it does not go through the Kreb’s cycle or the Electron Transport Chain. Therefore there are only 2 net ATP generated, not the net of 32 that come from cellular respiration.
Detailed explanation-3: -Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration.
