Which of the following statements describes enzyme cooperativity?
A) A multienzyme complex contains all the enzymes of a metabolic pathway.
B) A product of a pathway serves as a competitive inhibitor of an early enzyme in the pathway.
C) A substrate molecule bound to an active site of one subunit promotes substrate binding to the active site of other subunits.
D) Several substrate molecules can be catalyzed by the same enzyme.
E) A substrate binds to an active site and inhibits cooperation between enzymes in a pathway.
Enzyme polymorphism
Induced-fit model of enzyme activity.
Enzymes: Note the enzyme has the ending ase as in sucrase and the actual substrate is sucrose.
Sandwich or capture enzyme immunoassay for patient IgM (double capture: IgM capture, Ag capture).
