WebOptimum environment. As with all enzymes, pectinases have an optimum temperature and pH at which they are most active. For example, a commercial pectinase might typically be activated at 45 to 55 °C and work well at a pH of 3.0 to 6.5. Industrial Uses. Pectinase enzymes play various roles in both the fruit juice and wine industries. WebApr 23, 2024 · Optimum temperature: The temperature at which an enzyme shows its highest activity is called optimum temperature. Optimum pH: The pH at which an …

WebThe lower the pH (when lower than optimum), the less the enzyme function; the higher the pH (when higher than optimum), the less the enzyme works. Explain the effect of changes in temperature and pH on enzyme activity. As shown in the graph above, as the temperature rises, the enzyme activity slowly increases until about 37 o C. This is … WebSep 23, 2015 · The optimum temperature of the enzyme reaction was determined in the same substrate solution at various temperatures ranging from 35°C to 60°C. The optimal pH for lipase activity was determined by assaying the hydrolytic activity at pH ranging from 6.0 to 9.0, using an established spectrophotometric method [ 16 ]. WebAug 16, 2024 · An enzyme exhibits maximum activity over the narrow pH range in which a molecule exists in its properly charged form. The median value of this pH range is called the optimum pH of the enzyme (part (b) of Figure 18.7. 2 ).
