How is citric acid cycle regulated
WebCitrate synthase participates in the citric acid cycle (otherwise known as the TCA cycle), which follows glycolysis in aerobic organisms. In this cycle, acetate (as acetyl-coA) is successively oxidized to form carbon dioxide, driving the release of reducing agents NADH and FADH 2 (3). Web4 nov. 2024 · The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle, is the second stage of cellular respiration. This cycle is catalyzed by several enzymes and is named in honor of the British scientist Hans Krebs who identified the series of steps involved in the citric acid cycle.
