The chemical process that is happening is called fermentation.
<u>Explanation:</u>
Grapes contain a lot of carbohydrates, specially maltose. Maltose is a disaccharide, composed of two molecules of glucose. This maltose, when acted upon by yeast produces ethanol. The process going in is called fermentation. Here one molecule of glucose undergoes the process of glycolysis which leads to formation of two molecules of pyruvate.
These pyruvates are acted upon by alcohol dehydrogenase to form two molecules of ethanol and two molecules of carbon dioxide. Thus we can see bubbles coming out of the solution. Yeasts die as the alcohol concentration reaches around 13 to 14% v/v.
The main function of the large central vacuole in plant cells is to provide structural support; however, it serves other functions such as protection, storage, growth and waste disposal.
Fungi reproduce asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Somatic cells in yeast form buds.
