单词 | citric acid cycle |
例句 | The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP. Concepts of Biology 2013-04-25T00:00:00Z Certain nonessential amino acids can be made from intermediates of both glycolysis and the citric acid cycle. Biology for AP Courses 2022-06-09T00:00:00Z Under aerobic conditions, pyruvate enters the Krebs cycle, also called the citric acid cycle or tricarboxylic acid cycle. Anatomy and Physiology 2013-06-19T00:00:00Z Krebs won the medal in 1953 when the Nobel Prize for Physiology or Medicine was divided equally between Krebs, for his discovery of the citric acid cycle, and Fritz Lipmann, for work on enzymes. Nobel medal to be auctioned to help train scientists 2015-07-09T04:00:00Z The genes encode enzymes that act in an energy-producing metabolic pathway called the citric acid cycle. Metabolic quirks yield tumour hope 2014-04-09T17:20:17.678Z Cholesterol synthesis starts with acetyl CoA, and the components of triglycerides are picked up by acetyl CoA and enter the citric acid cycle. Concepts of Biology 2013-04-25T00:00:00Z An increase in citrate concentration can occur because of a blockage in the citric acid cycle. Biology for AP Courses 2022-06-09T00:00:00Z Several of the intermediate compounds in the citric acid cycle can be used in synthesizing non-essential amino acids; therefore, the cycle is both anabolic and catabolic. Concepts of Biology 2013-04-25T00:00:00Z Other molecules that would otherwise be used to harvest energy in glycolysis or the citric acid cycle may be removed to form nucleic acids, amino acids, lipids, or other compounds. Concepts of Biology 2013-04-25T00:00:00Z How does citrate from the citric acid cycle affect glycolysis? Biology for AP Courses 2022-06-09T00:00:00Z Like the conversion of pyruvate to acetyl CoA, the citric acid cycle in eukaryotic cells takes place in the matrix of the mitochondria. Concepts of Biology 2013-04-25T00:00:00Z The citric acid cycle is a series of redox and decarboxylation reactions that remove high-energy electrons and carbon dioxide. Biology for AP Courses 2022-06-09T00:00:00Z Fatty acids can feed into the citric acid cycle. Biology for AP Courses 2022-06-09T00:00:00Z Which of the following best describes how the citric acid cycle relates to glycolysis, oxidative phosphorylation, and chemiosmosis? Biology for AP Courses 2022-06-09T00:00:00Z In the mitochondria, acetyl CoA continues on to the citric acid cycle. Biology for AP Courses 2022-06-09T00:00:00Z Two carbon atoms come into the citric acid cycle from each acetyl group. Concepts of Biology 2013-04-25T00:00:00Z A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids. Biology for AP Courses 2022-06-09T00:00:00Z The citric acid cycle occurs in the mitochondrial matrix and involves a series of redox and decarboxylation reactions that again remove high energy electrons and produce CO2. Biology for AP Courses 2022-06-09T00:00:00Z Almost all of the enzymes of the citric acid cycle are soluble, with the single exception of the enzyme succinate dehydrogenase, which is embedded in the inner membrane of the mitochondrion. Biology for AP Courses 2022-06-09T00:00:00Z Unlike glycolysis, the citric acid cycle is a closed loop: The last part of the pathway regenerates the compound used in the first step. Biology for AP Courses 2022-06-09T00:00:00Z Fatty acids are broken into two-carbon units that enter the citric acid cycle. Concepts of Biology 2013-04-25T00:00:00Z They energize the acetyl group in the citric acid cycle. Biology for AP Courses 2022-06-09T00:00:00Z If this transfer does not occur, the oxidation steps of the citric acid cycle also do not occur. Biology for AP Courses 2022-06-09T00:00:00Z Note that the citric acid cycle produces very little ATP directly and does not directly consume oxygen. Biology for AP Courses 2022-06-09T00:00:00Z The last step in the citric acid cycle regenerates oxaloacetate by oxidizing malate. Biology for AP Courses 2022-06-09T00:00:00Z They energize the entry of the acetyl group into the citric acid cycle. Concepts of Biology 2013-04-25T00:00:00Z |
