Zeile and Hellström’s data show that a molecule of catalase at 0°C. catalyses the destruction of about 2 × 105 H2 O2 molecules per second. The mean life of an active catalase-hydrogen peroxide molecule is about 10-7 second. The velocity constant for the union of catalase and hydrogen peroxide exceeds 7 × 106 . These values are compared with similar data relating to other enzymes and to hæmoglobin.
