WAS BEDEUTET KREBS CYCLE AUF ENGLISCH
Zitronensäurezyklus
Der Zitronensäure-Zyklus - auch bekannt als der Tricarbonsäure-Zyklus oder der Krebs-Zyklus, - ist eine Reihe von chemischen Reaktionen, die von allen aeroben Organismen verwendet werden, um Energie durch die Oxidation von Acetat zu erzeugen, das von Kohlenhydraten, Fetten und Proteinen in Kohlendioxid und Chemikalien abgeleitet ist Energie in Form von Adenosintriphosphat. Darüber hinaus bietet der Zyklus Vorläufer bestimmter Aminosäuren sowie das Reduktionsmittel NADH, das in zahlreichen anderen biochemischen Reaktionen verwendet wird. Seine zentrale Bedeutung für viele biochemische Wege deutet darauf hin, dass es eine der frühesten etablierten Komponenten des Zellstoffwechsels war und abiogenisch entstanden sein könnte. Der Name dieses Stoffwechselweges leitet sich von Zitronensäure ab, die verbraucht wird und dann durch diese Sequenz von Reaktionen regeneriert wird, um den Zyklus abzuschließen. Darüber hinaus verbraucht der Zyklus Acetat und Wasser, reduziert NAD + auf NADH und produziert Kohlendioxid als Abfall Nebenprodukt. Die durch den TCA-Zyklus erzeugte NADH wird in den oxidativen Phosphorylierungsweg eingespeist. Das Ergebnis dieser beiden eng verknüpften Wege ist die Oxidation von Nährstoffen zur Herstellung von nutzbarer chemischer Energie in Form von ATP.
Definition von Krebs cycle im Wörterbuch Englisch
Die Definition von Krebs Zyklus im Wörterbuch ist ein Stadium der Gewebeatmung: eine Reihe von biochemischen Reaktionen in Mitochondrien in Gegenwart von Sauerstoff, mit denen Acetat, aus dem Abbau von Lebensmitteln abgeleitet, in Kohlendioxid und Wasser umgewandelt wird, mit der Freisetzung von Energie Auch genannt: Zitronensäurezyklus, Tricarbonsäurezyklus.
