usually cooking:
yeast (a bacteria) ferments in dough during baking- bread produced
Grape Juice ferments- wine is produced
milk ferments- yogurt is produced.

Humans use fermentation for various purposes such as producing Alcoholic Beverages like beer and wine, baking to make bread rise, pickling to preserve vegetables, and producing dairy products like yogurt and cheese. Fermentation is also used in the pharmaceutical and biotechnology industries to produce antibiotics, insulin, and other chemicals.
Fermentation can benefit humans by producing foods like yogurt, kimchi, and pickles that contain beneficial probiotics which support gut health. Additionally, fermentation can increase the bioavailability of nutrients in certain foods, making them easier for the body to absorb. On the other hand, excessive consumption of fermented foods high in salt or sugar can have negative impacts on health.
Humans use bacteria in the fermentation process to produce products like yogurt, cheese, and sauerkraut. Bacteria are used in sewage treatment plants to break down organic matter and purify water. Some bacteria are used in biotechnology to produce insulin, antibiotics, and other pharmaceuticals.
No, not all body cells always use cellular respiration and fermentation. Different cells in the body have different energy needs and can switch between these processes depending on factors such as oxygen availability and energy requirements. Cells like muscle cells primarily use aerobic respiration, while certain microorganisms and muscle cells can use fermentation in the absence of oxygen.
It depends on the exact definition of "fermentation"; people differ on this. Yeasts, plants under anaerobic conditions (e.g. waterlogged soils), and some bacteria can convert sugars into ethanol.
In humans, long distance running can lead to the production of lactic acid through lactic acid fermentation. This process occurs when the body cannot supply enough oxygen to the muscles during intense exercise, causing them to switch to anaerobic metabolism to generate energy.
