BIOC 2580 Lecture Notes - Lecture 20: Succinic Acid, Acetyl-Coa, Anabolism
Document Summary
We have discussed about beta oxidation and glycolysis. These are but the first stages of fatty acid and glucose catabolism respectively. Some organisms and certain cells obtain energy exclusively through the anaerobic breakdown of glucose to lactate or ethanol. However, most eukaryotic cells obtain their energy through the complete oxidation of organic fuels into co2 and. This aerobic phase of catabolism is known as respiration. H. a. krebs and w. a. johnson, article in. The citric acid cycle constitutes the second stage of cellular respiration. The citric acid cycle also supplies or consumes many important intermediates derived from, or converted into, amino acids, nucleotides, and other key materials. The great hungarian biochemist albert szent-gy rgyi (who won the nobel. Prize in 1937 for the discovery of vitamin c) was one of the pioneers whose studies led to the concept of the citric acid cycle.
