The Main Goal of Fermentation Is to Sustain ATP Production

Multiple Choice

The main goal of fermentation is to sustain ATP production by glycolysis. This is accomplished by

A) passing the electrons on NADH to pyruvic acid, regenerating NAD+ so glycolysis can continue.
B) enables the cell to use its respiratory chain without oxygen being available.
C) producing acids and alcohols which the microorganism can use as an alternative nutrient source when glucose is not available.
D) producing acids which lower cellular pH to promote more efficient ATP recharge.
E) diverting glycolysis intermediates into the pentose phosphate pathway.
