Comparison of biocatalysts with chemical catalysts!
4, some of the catalytic activity of biological enzymes and related factors .5, most of the enzymes are proteins, which will be high temperature, strong acid, alkali and other broken
biocatalyst activity is adjustable, can be subject to hormones and other active regulation of hormones.
(1) The chemical reaction catalyzed by the biological enzyme is generally carried out under relatively mild conditions. (2) The enzyme has the highest activity at the optimum temperature and pH, and the temperature of the biocatalyst is more moderate. And PH high or low, the enzyme activity will be significantly reduced.In general, the animal in the enzyme the optimal temperature between 35 ~ 40 ℃; plant enzyme in the optimal temperature between 40 ~ 50 ℃; animal body Of the enzyme most of the most suitable pH between 6.8.0, but there are exceptions, such as the optimal pH of pepsin 1.5; plant enzymes in the most suitable pH between 4.6.5. (3) acid, Or the temperature is too high, the enzyme structure will be destroyed, so that the enzyme permanently inactivated .0 ℃ or so, the enzyme activity is very low, but the spatial structure of the enzyme is stable, at the appropriate temperature of the enzyme activity can be increased The
Differences: 1, the biocatalyst has a higher efficiency of the catalytic capacity; its efficiency is the general inorganic catalyst 10 of the power of 10 ~ 10 13 power.
The same point: biocatalysts and chemical catalysts are selective (specific) and efficient; participate in each reaction, its own nature and quantity will not change.
