Question

Fermentation is _____________. It uses _________ and releases CO2 and ____________ if it is yeast or ___________ if it is a muscle. Fill in the blanks in the order they appear.

(A): aerobic, pyruvic acid, lactic acid, alcohol
(B): anaerobic, glucose, alcohol, lactic acid
(C): anaerobic, pyruvic acid, lactic acid, alcohol
(D): anaerobic, pyruvic acid, alcohol, lactic acid

Answer 1

Fermentation can be seen in the rising of dough, the making of wine and other alcohols, and the burning feeling in your legs after running.

So the answer is D: Fermentation is anaerobic. It uses pyruvic acid and releases CO2 and Alcohol if it is yeast and lactic acid if it is a muscle.

Answer 2

Fermentation is referred as an energy yielding anaerobic metabolic process.The fermentation of pyurvic acid by yeast produces ethanol(alcohol).An example of this process would be Beer production and sparkling wines. In muscles, lactic acid is produced by fermentation.So the answer is D.
