Depending upon the nature of chemical group which they carry, the [...]
The following points highlight the seven major factors affecting the enzyme activity. The factors are: 1. Temperature 2. Hydrogen Ion Concentration (pH) 3. Water 4. Concentration of the Substrate 5. Enzyme Concentration 6. Inhibitors 7. Accumulation of End-Products. Factor # 1. Temperature: Usually the activity of the enzymes is optimum at normal body temperature at very low temperature (i.e., about [...]
