Nabothian cysts are tiny cysts that form on the surface of the neck of the womb (cervix). Nabothian cysts are filled with fluid (mucus), which is secreted by the glands of your cervix. These cysts can range in size from just a few millimetres to four centimetres wide.
Therefore, in anaerobic conditions, some organisms perform fermentation, which is a process that anaerobically generates ATP by performing glycolysis and one extra step. There are two types of fermentation we'll discuss in this lesson-lactic acid fermentation and alcoholic fermentation.hen in an anaerobic environment, some cells can use glycolysis and fermentation to keep producing ATP. Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.
Figure 7-23Fermentation in yeast produces ethyl alcohol. The carbon dioxide that isreleased during fermentation creates bubbles and pockets that make breadrise. The alcohol evaporates during baking. There are also fungi and bacteria that produce lactic acid duringfermentation, just as your muscle cells do.Humans use these microbes totransform milk into cheese and yogurt.hen yeast cells are kept in ananaerobic environmentâan environment without oxygenâthey areforced to ferment sugar and other foods. In contrast to fermentation inyour muscle cells, fermentation in yeast produces alcohol, instead oflactic acid, as a waste product (Figure 7-23).
