Question
Chemistry Question on Enzymes
The effectiveness of an enzyme is affected least by
A
temperature
B
concentration of the substrate
C
original activation energy of the system
D
concentration of the enzyme
Answer
original activation energy of the system
Explanation
Solution
The enzymes lower the requirement of activation energy for catalyzing a reaction and these are least affected by the original activation energy of the system. Enzymes are thermolabile. Increase in substrate concentration or enzyme concentration increases the rate of reaction.
