Detailed explanation-1: –In which cells does lactic acid fermentation occur?-The energy needed to win a 1-minute foot race comes primarily from which process? LACTIC ACID FERMENTATION. What is needed to convert pyruvic acid into lactic acid?
Detailed explanation-2: -Net ATP production when one molecule of glucose is fermented to alcohol or lactic acid: When glucose ferments, there is a net gain of two ATP molecules in the glycolysis process.
Detailed explanation-3: -Lactic acid fermentation can supply enough ATP to last about 90 seconds. However, extra oxygen is required to get rid of the lactic acid produced. Following intense exercise, a person will huff and puff for several minutes in order to pay back the built-up “oxygen debt” and clear the lactic acid from the body.
Detailed explanation-4: -Therefore, six ATP molecules are lost in the process of lactic acid fermentation.
