Which of the following statements is correct regarding enzymes saturated with substrate?
A
Increasing the substrate concentration will appreciably increase the reaction rate.
B
Any excess substrate will shift the equilibrium towards the product end of the reaction.
C
An enzyme with lower 
is more easily saturated than an enzyme with high 
.
is more easily saturated than an enzyme with high . D
At saturating levels of substrate, a competitive inhibitor will affect the reaction rate more than a non-competitive inhibitor.
Text Solution
Verified by ExpertsThe correct answer is:
C
is the Michaelis constant or Michaelis-Menten constant and can be defined as the concentration of substrate required to half saturate the enzyme or in other words to cause half the maximal reaction rate ( 
). Therefore, a low 
would indicate a high affinity, and therefore an enzyme with lower 
would be more easily saturated.
