In the enzyme activity of lactase lab, sodium carbonate was used to halt the enzyme-catalyzed reaction. Which of the following is the most likely explanation for sodium carbonate having this effect?
A. Sodium carbonate raises the kinetic energy of the solution
B. Sodium carbonate is a base and enzymes have an optimal pH range
C. Sodium carbonate is toxic and quickly destroys the enzyme
D. Sodium carbonate is able to lower the activation energy of the reaction
Homework Answers
Ans
Sodium carbonate act as alkali when it is dissolved in water then it form carbonic acid and strong sodium Hydroxide base that's why it change pH of medium and enzyme act in particular pH range that's why It halt enzyme catalysed reaction.
So option B is correct
