Muscle cells utilize lactic acid fermentation during physical activity when there is not enough oxygen available to produce energy through aerobic respiration. This typically occurs during intense exercise or when the body is under stress.
During intense physical activity, human muscle cells use lactic acid fermentation to produce energy when there is not enough oxygen available. This process converts glucose into lactic acid, releasing energy that can be used by the muscles for short bursts of activity.
During physical activity, the body uses ATP (adenosine triphosphate) stored in muscles for immediate energy. If the activity continues, the body breaks down glycogen stored in the muscles and liver to produce more ATP for sustained energy.
During intense physical activity, a muscle cell undergoes increased contraction and relaxation cycles. This leads to the breakdown of ATP to provide energy for muscle contractions. Additionally, there is an increased demand for oxygen and nutrients to support the cellular functions and remove waste products such as lactic acid.
Lactic acid fermentation occurs in certain organisms because it allows them to produce energy without using oxygen. This process helps them survive in low-oxygen environments and provides a quick source of energy during intense physical activity.
During physical activity, we sweat the most on areas of our body with a high concentration of sweat glands, such as the forehead, armpits, and back.

Because mammalian muscle cells are genetically programmed to perform lactic acid fermentation, not ethanol fermentation.

Fermentation
The measure of the amount of oxygen used by the body during physical activity is called VO2 max. VO2 max is the maximum volume of oxygen that a person can utilize during intense exercise. It is often used as an indicator of aerobic fitness.
Aerobic fitness is defined as the capacity to take in, transport, and utilize oxygen.

The measure of the amount of oxygen used by the body during physical activity is known as VO2 max. It represents the maximum volume of oxygen that an individual can utilize during intense exercise and is a key indicator of cardiovascular fitness and aerobic endurance. Higher VO2 max values typically indicate better physical fitness and performance potential in endurance sports.

During physical activity, you sweat the most on areas of your body with a high concentration of sweat glands, such as your armpits, forehead, and back.
Sweating usually starts during physical activity when your body temperature rises and needs to cool down.
