| 单词 | pyruvic acid |
| 例句 | In the first reaction, a carboxyl group is removed from pyruvic acid, releasing carbon dioxide as a gas. Concepts of Biology 2013-04-25T00:00:00Z Glycolysis is a sequence of chemical reactions that convert glucose to two three-carbon compounds called pyruvic acid. Biology for AP Courses 2022-06-09T00:00:00Z It occurs when the pyruvic acid that is formed from glycolysis is broken down in a series of reactions. Miller & Levine Biology 2018-01-01T00:00:00Z However, if oxygen is not available, pyruvic acid is converted to lactic acid, which may contribute to muscle fatigue. Anatomy and Physiology 2013-06-19T00:00:00Z An earlier version of this article misstated the definition of pyruvic acid. Vidalia Onions: A Crop With an Image to Uphold 2014-04-08T20:35:08Z Once the lactic acid has been removed from the muscle and is circulated to the liver, it can be converted back to pyruvic acid and further catabolized for energy. Concepts of Biology 2013-04-25T00:00:00Z Several enzymes in the cell are involved in converting glucose to pyruvic acid. Biology for AP Courses 2022-06-09T00:00:00Z At the beginning of the Krebs cycle, the three-carbon compound known as pyruvic acid created from glycolysis passes through the two membrane walls of the mitochondrion. Miller & Levine Biology 2018-01-01T00:00:00Z The inputs for aerobic respiration include glucose circulating in the bloodstream, pyruvic acid, and fatty acids. Anatomy and Physiology 2013-06-19T00:00:00Z The fermentation of pyruvic acid by yeast produces the ethanol. Biology for AP Courses 2022-06-09T00:00:00Z Prior to the start of the first step, a transitional phase occurs during which pyruvic acid is converted to acetyl CoA. Biology for AP Courses 2022-06-09T00:00:00Z Once the lactic acid has been removed from the muscle and circulated to the liver, it can be reconverted into pyruvic acid and further catabolized for energy. Biology for AP Courses 2022-06-09T00:00:00Z One carbon atom splits off from the pyruvic acid and forms carbon dioxide. Miller & Levine Biology 2018-01-01T00:00:00Z Oxygen is required to restore ATP and creatine phosphate levels, convert lactic acid to pyruvic acid, and, in the liver, to convert lactic acid into glucose or glycogen. Anatomy and Physiology 2013-06-19T00:00:00Z If oxygen is not available, pyruvic acid is converted to lactic acid, which may contribute to muscle fatigue. Anatomy and Physiology 2013-06-19T00:00:00Z If oxygen is available, pyruvic acid is used in aerobic respiration. Anatomy and Physiology 2013-06-19T00:00:00Z A carboxyl group is removed from pyruvic acid, releasing carbon dioxide as a gas. Biology for AP Courses 2022-06-09T00:00:00Z In the next stage, the Krebs cycle, pyruvic acid that was produced during glycolysis is broken down, and energy carriers are produced.
