Absorption of Carbon Dioxide by the Application of Carbonic Anhydrase. II : Effect of Enzyme on the Rate of Absorption of Carbon Dioxide by Magnesium Oxide
In order to accelerate the rate of absorption of carbon dioxide by magnesium oxide, carbonic anhydrase or red blood corpuscles were added to magnesium oxide suspended in water as an accelerator. The rate of absorption was increased with the increase of the concentration of carbonic anhydrase up to 24 mg per litre. But by adding more amount of the enzyme, little further acceleration of the absorption rate was observed. The rate of absorption was also increased with the concentration of magnesium oxide up to 20 g per litre, whether the enzyme was present or not. The enzyme action was almost independent of the particle size of the oxide. The optimum temperature of the absorption was 35℃ in the absence of the enzyme and 45℃ in its presence. The enzyme lost its activity at 80℃. Red blood corpuscles, used instead of the enzyme, increased also the absorption velocity
