|
|
It is the same for all enzymes

Detailed explanation-1: -Answer and Explanation: The correct answer: The optimum pH for an enzyme is d) Where it works best. Optimum pH for an enzyme is the specific pH at which the enzyme can work the best.
Detailed explanation-2: -Enzymes are affected by changes in pH. The most favorable pH value-the point where the enzyme is most active-is known as the optimum pH.
Detailed explanation-3: -As the temperature is increased enzyme activity increases to a maximum value at the optimum temperature (around 37 oC for most human enzymes).
Detailed explanation-4: -Enzymes function at an optimal pH where the highest activity can be observed. Outside this pH value, the activity of the enzyme decreases, and the rate of an enzyme-catalyzed reaction slows down.
