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.
Polymer quench: Polymer quenches that will produce a cooling rate in between water and oil. The cooling rate can be altered by varying the components in the mixture-as these are composed of water and some glycol polymers.
