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. WebThe citric acid cycle can be regulated in one of several different ways. We can regulate it indirectly by controlling pyruvate decarboxylation (which is the process that occurs before the citric acid cycle begins) or we can regulate it directly by controlling a few of the steps involved directly in the citric acid cycle. increase clicks
