Document Summary
In some cells, pyruvate can be fermented to lactate. o o o o. Our muscle cells do this when we exercise heavily. In yeast and some plant cells, pyruvate can be fermented to ethanol. o o o o. Alcoholic fermentation by yeast gives us alcoholic beverages. o. Why can the fermentation-base percent alcohol in beer and wine reach a max of. When it reaches that level, the cells die. When yeast cells are exposes to a lot of ethanol, it makes the cell membrane more porous. o o. Except our body changes that factor of it so it doesn"t do it in our cells. Researches are working to improve the alcohol tolerance of yeast. The next step in catabolism depends on the presence or absence of a final electron acceptor. o o. Instead of ethanol fermentation, our body does lactate fermentation. When you lose weight, where does the mass go? o o.
