A1 - Warburg, O. T1 - An electrochemical demonstration of the energy cycle and maximum quantum yield in photosynthesis JF - Biochimica et Biophysica Acta N2 - 1. The electrochemical method of Tödt for the determination of oxygen gas has been applied to the measurement of (1) the quantum requirement of photosynthesis and (2) the course of the light reaction and the dark back-oxidation over very short time periods (seconds). 2. With this new and independent, galvanometric method, the earlier results obtained by us with manometry have been confirmed, that is, attainment of a limiting quantum requirement of about 3 in the cycle of light and dark reactions. All significant objections raised regarding the time lag of manometry, as used by us, are thereby refuted. 3. Quantum requirements with single illumination periods as short as 5 seconds have been reported, and much shorter periods are shown possible. 4. The new electrochemical method opens up a field of investigation closed, on a time basis, to manometry. Nevertheless, manometry, with which the energetics of photosynthesis was discovered, can never be given up: for it alone of all methods gives information about both gases, oxygen and carbon dioxide. N2 - 1. Die elektrochemische Methode von Tödt zur Bestimmung von gasförmigem Sauerstoff wurde auf die Messung (1) des Quantenbedarfs der Photosynthese und (2) des Verlaufs der Lichtreaktion und der Dunkelreaktion (Rückoxydation) während sehr kurzer Zeiträume (Sekunden) angewandt. 2. Mit dieser neuen und unabhängigen galvanometrischen Methode wurden die früheren von uns durch manometrische Messungen erhaltenen Ergebnisse bestätigt, nämlich die Erreichung eines Grenzquantenbedarfs von ungefähr 3 im Cyclus der Licht- und Dunkelreaktion. Alle bedeutenden, auf Grund der Zeitverschiebung bei der von uns benützten manometrischen Messung erhobenen, Einwände wurden hierdurch widerlegt. 3. Es wurde der Quantenbedarf für einfache Beleuchtungsperioden von 5 Sekunden berichtet und es wurde gezeigt, dass noch viel kürzere Beleuchtungsperioden möglich sind. 4. Die neue elektrochemische Methode eröffnet ein für manometrische Untersuchungen wegen der erforderlichen Zeit unerschlossenes Gebiet. Nichtsdestoweniger können manometrische Untersuchungen, mit denen die energetischen Beziehungen der Photosynthese entdeckt wurden, nie aufgegeben werden, denn von allen Methoden geben sie allein sowohl über Sauerstoff wie über Kohlendioxyd Aufschluss.
