Lactic Fermentation vs. Alcohol Fermentation: What's the difference?

Answer 1

lactic acid fermentation is a form of anaeorobic respiriation that occurs in animals cells in the absence of oxygen while alcohol fermentation is the form of anaeorobic respiration of some microbial agent mostly yeasts in converting sugars into ethanol.

Answer 2

The difference between them is the product of the fermentation reaction. That difference comes from the organism which is carrying out the fermentation.

In both cases, pyruvic acid is used to accept electrons from NADH. Some organisms (like humans) have an enzyme that can reduce pyruvic acid to lactic acid. Other organisms have the enzymes that can convert pyruvic acid first into acetaldehyde and CO2, and then another enzyme that can reduce acetaldehyde to ethanol.

Answer 3

In alcohol fermentation one pyruvic acid molecule produce one ehonol and one carbondioxode molecules
but in lactic acid fermentation one pyruvic acid gives one lactic acid only , no carbondioxied is released
