but in the case of chemical digestion, it breaks the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.

Answer: Lactic acid fermentation
Explanation:
The lactic acid fermentation can be defined as the process by which sugar is being converted into lactic acid.
There is no emission of carbon dioxide during the whole process. In case of curd formation. The bacteria convert the milk into curd and provides it a sour taste.
It is converted by help of bacteria known as Lactobacillus acidophillus. This method is very frequently in many of food processing industry.
The small cells of bacteria that lack nuclei are termed as PROKARYOTIC CELLS.
Prokaryotic cells are the bacterial cells that do not have true nucleus. These cells contain genetic material naked in the cytoplasm and is referred as nucleoid that lacks a nuclear membrane.
Chromatin is the lose form of genetic material & the "normal state" of DNA, RNA, and protein in the nucleus and in the cells.
Chromosomes are a condensed form of chromatin. Chromatin becomes chromosomes in the Prophase of Mitosis and Prophase 1 and Prophase 2 of Meiosis. It loosens again in the Telophase in Mitosis and Telophase 1 and Telophase 2 in Meiosis.
Sister Chromatids are made when chromosomes replicate during the cell cycle. The replication leads to the formation of the chromatids. The chromatids are joined by a single centromere. They separate during Anaphase 2 of meiosis.
I hope that this helps! Sorry if it doesn't I tried my best to explain!
