Process that makes ethanol is called - Answer Fermentation
Fermentation makes (Only/Others as well as) Ethanol - Answer Others as well as, like
phenols
what % ethanol is toxic to yeasts - Answer 15%
What technique is used when alcohol concentration needs to be more than 40% -
Answer Distillation
Production of ethanol outline - Answer Glucose -> 2ATP and 2 pyruvate +2 NADH
2 pyruvate-> 2 Acetaldehyde + 2 CO2
2 Acetaldehyde + 2NADH --Alcohol dehydrogenase---> 2 Ethanol
Ways to measure alcohol concentration - Answer Proof and alcohol by volume
ABV calculation - Answer 131.25 * (Original sugar Conc-Final sugar conc)
Common additional molecules in liquor - Answer Anthocyanins

Ethanol is mostly absorbed in X with some in Y - Answer X=SI
y=stomach
Food (increase/Decrease) retention of ethanol in stomach, which causes X - Answer
Increases, Slower absorption

BAC units - Answer g/100mL
Average man is x% water and Woman is y% water - Answer 53.4% and 48.5%
Blood is x% water - Answer 80.6% (multiply during BAC calculations)
Larger people have (lower/higher) BAC - Answer Lower
Leaner people have (lower/higher) BAC - Answer Lower
Is the number of drinks consumed a more reliable measure of intoxication than BAC? -
Answer No
