2 True/False Question

1. Alcohol → in the absence of oxygen, yeast and a few other microrganisms use alcoholic fermintation, forminig ethyl alcohol and carbon dioxide as wastes
   

   True        False

2. The Krebs Cycle → pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
   

   True        False
