In muscle cells, fermentation produces _____.
A: Carbon dioxide, ethanol, NADH, and ATP
B: Carbon dioxide, ethanol, and NAD+
D: Lactate, NADH, and ATP
E: Lactate and NAD+
The correct answer is Lactate and NAD+.
In muscle cells, fermentation produces lactate and NAD+.
Fermentation is a process in which an organism converts carbohydrates into an acid or alcohol. In fermentation, carbohydrates such as sugar and starch are converted. Bacteria convert carbohydrates into lactic acid through fermentation.
In fermentation, pyruvate (pyruvic acid) from glycolysis converts into lactic acid. In this process, from NADH, NAD+ produces. In turn, NAD+ results in additional molecules of ATP.
When we work fast and hard, this fermentation used in muscle cells.
In fermentation, the extraction of the energy molecule from the carbohydrate source occurs without oxygen. It is basically happening in the muscle cell.
In muscle cells, this process occurs during the vigorous activity during which the supply of oxygen to the associated cells is very limited. As a result of this process, lactic acid produce which provide the required energy to the body during intense physical activity.
Whenever we run or indulge in any other intense physical activity, we feel sore and tired afterward. As a result, Lactic acid produces in the body. It is because muscle cells use fermentation of lactic acid for energy. Because of lactic acid formation in the body, we soreness and tiredness in the body.
