Anna’s mother prepares sauerkraut, a fermented dish made from finely cut cabbage and salt. Lactobacillus bacteria present on the surface of the cabbage combine with salt to turn the cabbage into a crunchy, sour dish. What chemical process occurs to create this dish?
A.
alcoholic fermentation
B.
cellular respiration
C.
conservation
D.
lactic acid fermentation
E.
photosynthesis

Respuesta :

The correct answer is - D. lactic acid fermentation.

The sauerkraut is finely cut cabbage, put in water with lot of salt, and left for some time so that the final dish is ready. While the sauerkraut is left like this, the lactobacillus bacteria gets in action, starting the process of lactic acid fermentation, process in which the glucose and the other six-carbon sugars are converted into cellular energy and the metabolite lactate. This type of fermentation is an anaerobic fermentation process, and it is not used only for the sauerkraut, but for lot of vegetables, especially in Eastern Europe.

Answer:

The chemical process occurs to create this dish is fermentation.

Explanation:

Fermentation is defined as chemical process in which substance is broken down by the action of microorganism like bacteria, yeast etc into simpler or smaller molecules like alcohols or acids.

Lactobacillus bacteria present on the surface will help in breaking down of the carbohydrate or sugar present in cabbage to convert it into acid which is responsible for the sour taste of the dish.
