September 2008 : In the summer of 1865, noted American newspaperman and politician Horace Greeley penned, in an editorial, an admonishment to young civil servants in Washington DC. Greeley urged those who complained of low pay grades in the Capitol area to âGo west, young man!â.
When your muscles can't get enough oxygen during a short burst of exercise, they start to make use of a pathway called lactic acid fermentation, which generates a small three-carbon compound called lactic acid or lactate as a byproduct of glucose breakdown.
However, muscle cells have the ability to produce a small amount of ATP through glycolysis in the absence of oxygen. The muscle cells convert glucose to pyruvic acid. Then an enzyme in the muscle cells converts the pyruvic acid to lactic acid.As in the yeast, this reaction frees up the NAD while providing the cells with two ATP molecules from glycolysis.he muscle cells convert glucose to pyruvic acid.
