Champagne has bubbles in it because:  a. champagne grapes contain less sugar in them than wine grapes  b. additional sugar is added to wine in the champagne bottle before it is sealed  c. fermentation produces lactic acid in champagne instead of ethanol which is produced in making wine  d. wines with CO2 bubbles are lower calorie beverages than wines without CO2 bubbles  e. CO2 is produced in a 1:1 ratio to ethanol in the second fermentation which occurs in the champagne bottl

Humans cells performing fermentation create lactic acid which is toxic to cells. Select one: True False

The fermentation of glucose . . . A   produces less ATP than respiration. B   always results in alcohol production. C   only occurs in bacteria. D   is accomplished by mitochondrial enzymes.

The label on Vodka says that it is 40% ABV (alcohol by volume).  In comparison, red wine contains 10% ABV (alcohol by volume). From this information I can conclude that:  a. the potatoes from which vodka is made contain more carbohydrates to produce alcohol than do wine grapes  b. the yeast made to produce vodka must not be killed by concentrations of alcohol above 10-15% ABV  c. the alcohol in vodka is concentrated by distillation after fermentation  d. vodka is made by letting water evaporate after fermentation  e. vodka has fewer calories in 1.5 oz serving than a 6 oz serving of wine.
