Which of the following correctly compares alcoholic fermentation and lactic acid fermentation?

A.) Both provide NAD+ for glycolysis, but only lactic acid fermentation starts with pyruvic acid.
B.) Both result in substantial ATP molecules during anaerobic conditions, but neither creates much NAD+.
C.) Both result in NAD+ for glycolysis and fewer ATP molecules than cellular respiration
D.) Both produce fewer ATP molecules than cellular respiration, but only alcoholic fermentation results in NAD+.

C is the answer....fermentation is the process by which pyruvate is used as a subtrate for production of  lactate and ethanol. nadh produced from glycolysis is used to produce nad+  which can then be used to activate glycolysis...and produces very little  ATP
