Lactic acid fermentation differs from ethyl alcohol fermentation in that

A. In ethyl alcohol fermentation CO2 is also produced

B. Lactic acid fermentation can occur in all living things

C. Ethyl alcohol fermentation can only occur in plants

C. Only lactic acid fermentation can produce more ATP

I believe the answer is that in ethyl alcohol fermentation CO2 is also produced. The end product of ethyl alcohol fermentation has only 2 carbons, where the end product of lactic acid fermentation. Lactic acid fermentation is a metabolic process by process by which glucose and other six-carbon sugars are converted into cellular energy and metabolite lactate. Alcohol fermentation is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular producing ethanol and carbon dioxide as a by-product.
