ON BIOLOGICAL OXIDATIONS AS FUNCTION OF TEMPERATURE

摘要: 1. The critical thermal increments are calculated for respiratory processes (O(2) consumption, CO(2) production) in various plants and animals. They characteristically found to be of two, possibly three, types: micro = 11,500, 16,100 or 16,700. first is commonly encountered above 15 degrees , the second below that temperature, but these relations may reversed. (The value significantly changed inanition.) 2. For reduction methylene blue by bacteria, through removal H from succinic acid, This process (Quastel Whetham, 1924) at constant temperature a function hydroxyl ion concentration. suggestive identity pointed out increment this phenomenon with deduced biological respirations which dehydrogenation mechanism supposed widespread occurrence, connection Fe very likely has catalytic role. action OH' believed revealed frequently obtained respiration. 3. A somewhat lower (16,140) associated oxidation Fe'', compared (1) respiration sea urchin eggs, (Warburg) iron catalyst, (2) some simple reactions known serve as catalyst; it not oxidative involved. 4. bearing findings discussed relation theory functional analysis concurrent catalyzed protoplasm. It shown number activities effects safely assumed, values consistent those determined 5. further development views lead an extremely important method identifying controlling undisturbed living matter.
