Are fermentation reactions intracellular or extracellular? Explain.
kenny6666 [7]

Answer: Yes.

Explanation:

Fermentation is a general term denoting anaerobic degradation of glucose or other organic nutrients in various products to obtain energy in the form of ATP. Fermentation occurs when, after glycolysis, the Krebs cycle is not performed, because the organism does not have it or because this pathway is blocked, such as during hypoxia (lack of oxygen). Fermentation is a process used by bacteria to obtain energy, does not use oxygen and occurs in the cytoplasm of cells, ie an intracellular process, and each step is catalyzed with the help of different enzymes.

Some industries use this process in the production of some products, known to all of us, such as:

1. yogurt is produced by the famous lactic fermentation, where bacteria called lactobacilli to produce lactic acid.

2. bread and beer are produced by alcoholic fermentation, where the fermentation is carried out by fungi (facultative anaerobic), which ultimately produce alcohol;

3. vinegar to that produced by acetic fermentation, which consists of a chemical reaction, where partial oxidation of ethyl alcohol occurs, obtaining acetic acid.

How did people acquired immunity to a disease before the development of vaccines
djyliett [7]

Answer:

Exposure to the disease

Explanation:

Before vaccines,  the only way to develop immunity to a disease was to be exposed to the disease-causing pathogen without being harmed by it. A good example of this is smallpox, which was also the first vaccine developed. It was noticed that milk maids weren't catching and dying from small pox like everyone else, because they had been exposed to cowpox. This premise was used to create the first vaccine.

Vaccines give you immunity by injecting you with a small amount of a (usually inactive) pathogen. inside your body.  This means your immune system produces antibodies against it. Similar to what happened with the milkmaids.
