Glycolysis involved in glycolysis. The burning sensation in muscles during hard exercise can be attributed to the release of hydrogen ions during the shift to glucose fermentation from glucose oxidation to carbon dioxide and water, when aerobic metabolism can no longer keep pace with the energy demands of the muscles. These hydrogen ions form a part of lactic acid. The body falls back on this less efficient but faster method of producing ATP under low oxygen conditions. This is thought to have been the primary means of energy production in earlier organisms before oxygen reached high concentrations in the atmosphere between
This Is an Exercise This Is an Exercise This Is an Exercise is an album by experimental electropop artist Anna Oxygen, released in 2006 on Kill Rock Stars. Allmusic described the album as "just as fascinating as it is chilly and alienating. In her songs, Oxygen explores some of the same issues of authenticity, creation, and consumption that Tracy + the Plastics do, but with a sci-fi/fantasy bent." Oxygen composed the album herself, also handling piano, primary vocals, and sequencing. It also featured Melissa Collins on cello, Andy Gertz on accordion, and guest vocalists Kitty Jenson, Mirah Yom Tov Zeitlyn & Ginger Takahashi. Portland
