Which of the following will increase enzyme activity?
A) increase the temperature to boiling
B) decrease the concentration of the enzyme
C) alter the substrate
D) change to optimum pH for the reaction
E) decrease the temperature
Optimum pH
Optimum pH is the specific pH level at which an enzyme or biochemical reaction is most active, facilitating the highest rate of reaction.
Enzyme Activity
Enzyme activity refers to the rate at which an enzyme catalyzes a chemical reaction, influenced by factors such as temperature, pH, and substrate concentration.
Substrate
A substance or layer that underlies something, or on which some process occurs, particularly in biology and chemistry.
- Understand the basic principles of enzyme activity and how factors like temperature, pH, and substrate concentration affect it.

Final Answer :
D
Explanation :
Enzymes have an optimal pH range where they work the most efficiently. Changing to the optimum pH for the reaction will increase enzyme activity. Increasing the temperature to boiling (A) will denature the enzyme and decrease activity. Decreasing the concentration of the enzyme (B) will decrease activity. Altering the substrate (C) may or may not have an effect on activity, depending on the specific enzyme and substrate. Decreasing the temperature (E) may slow down but not necessarily increase enzyme activity.
