what determines the products of fermentation to be either alcohol or lactic acid?
Answers
oxygen determines the product of fermentation will be alcohol or lactic acid
Answer:
The Fermentation process product majorly depends upon the availability of oxygen to be either alcohol in yeast cells or lactic acid in our muscles.
Explanation:
Fermentation in the absence or lack of oxygen gas, results in the formation of products other than pyruvic acid.
In the case of yeast cells, the fermentation process that takes place in absence of oxygen results in the formation of alcohol mainly ethanol and carbon dioxide.
While referring to the case of our muscles, in the unavailability of the oxygen gas the fermentation of sugar leads to the production of lactic acid in our muscles.
It is also the major cause of the heavy cramps that occur after heavy exercise.
