Question

For how long can muscles rely soley on lactic acid fermentation to generate ATP

Answer 1

For most muscle activities it usually lasts at least 90 seconds in duration for you to solely rely with lactic acid.

Answer 2

The correct answer is: 90 seconds.

Step-by-step explanation:

Lactic acid fermentation occurs in muscle cells as a way to produce ATP when there's no oxygen around. After glycolysis, the pyruvic acid is converted into lactic acid.

Depending on the amount of time spent on an exercise, the energy used by the muscles can differ: for quick bursts of energy, the muscles cells use the ATP from lactic acid fermentation; to exercise for a longer period of time, the ATP comes from cellular respiration.

The ATP generated by lactic acid fermentation can last up to 90 seconds.
