Final answer:
Lactic acid fermentation can be recognized by the production of lactic acid as the end product, while alcoholic fermentation can be recognized by the production of alcohol, usually ethanol, as the end product.
Step-by-step explanation:
Lactic acid fermentation and alcoholic fermentation are two types of fermentation. Lactic acid fermentation can be recognized by the production of lactic acid as the end product. It occurs in certain bacteria, like the ones found in yogurt, and also in our muscle cells when they work hard and fast. On the other hand, alcoholic fermentation can be recognized by the production of alcohol, usually ethanol, as the end product. It occurs in yeast and some bacteria.
