The lactic acid diffuses out of the muscles and is taken to the liver by the blood. The liver can change lactic acid back into glucose: however, this conversion also requires the use of ATP. During strenuous exercise, primarily the muscles and not the liver use the oxygen, so the lactic acid accumulates.
/quenchÂ·ing/ (kwenchÂ´ing) 1. suppressing or diminishing a physical property, as of heat in a metal by immersion in cold liquid. 2. decrease of fluorescence from an excited molecule by other molecules that absorb some emission energy that would otherwise occur as light.
Quench C hardening is a mechanical process in which steel and cast iron alloys are strengthened and hardened. These metals consist of ferrous metals and alloys. This is done by heating the material to a certain temperature, depending on the material.uench metals is a progression; the first step is heating, i.e. heating it to the required temperature. Second step is soaking. Soaking can be done by air (air furnace), or a bath or in a vacuum. The soaking time in air furnaces should be 1 to 2 minutes for each millimeter of cross-section.
