Y but the enzyme cannot bind X and Y at the same time. Which of the following
statements are TRUE?
Multiple answers: Multiple answers are accepted for this question
Select one or more answers and submit. For keyboard navigation... SHOW MORE V
The Km for X will be affected if Y is present in the reaction mixture.
a
Y is a competitive inhibitor of X.
The Km for X will increase.
d.
The V for X will be affected if Y is present in the reaction mixture.
max
pH dependence of Vmax reflects the ionization state of catalytic site
e
residues.
Consider the following: X and Y are methanol (poisonous) and ethanol
respectively. If the Km for X = 0.01 M and the Km for Y = 0.001 M then
0.01 M Y is 10 times the concentration of Y required for 0.5 Vmax.
Addition of an enzyme to a chemical reaction increases the ratio of
