B)Glycolysis
C)The electron transport system
D)Fermentation

Question

Quizplus · Accepted Answer

Glycolysis occurs first in the process of anaerobic fermentation. Glycolysis breaks down glucose into two pyruvate molecules, which can then be used to undergo fermentation in the absence of oxygen. The Krebs cycle and electron transport system both require oxygen and do not occur in anaerobic fermentation. Fermentation is the final step in anaerobic fermentation, but it requires the production of pyruvate from glycolysis first.
