Question

biochemists consider the citric acid cycle to be the central reaction sequence in metabolism. One of the key steps is an oxidation catalyzed by the enzyme isocitrate dehydrogenase and the oxidizing agent NAD+. Under certain conditions, the reaction in yeast obeys 11th-order kinetics:
rate= k[enzyme][isocitrate]^4[AMP]^2[NAD+]m[Mg2+]^2
What is the order with respect to NAD+?

Answer 1

11=4+2+m+2
Solve for m

Answer 2

12

Answer 3

answer is 2

11= 1 + 4 + 2 + m + 2
solve for m.

the overall order is found by adding all of the other orders together. the overall order is given so you need to subtract all of the known orders to get m. k[enzyme] has an order of 1.
