This does not release so much energy and it produces much more toxic waste products. However, if Oxygen is not available, anaerobic respiration is better than nothing. When this happens in our muscles we produce lactic acid which gives you cramp. The bacteria in milk produce the same chemical when they turn it sour. So lactic acid is the acid in sour milk.
Yeasts produce alcohol which is also toxic.
Eventually there will be so much alcohol that the yeast cannot survive. Copyright 1997 - 2000 Gondar Design. All rights reserved.
