Which of the following is an example of cooperativity?
A) the binding of an end product of a metabolic pathway to the first enzyme that acts in the pathway
B) one enzyme in a metabolic pathway passing its product to act as a substrate for the next enzyme in the pathway
C) a molecule binding at one unit of a tetramer, allowing faster binding at each of the other three
D) the effect of increasing temperature on the rate of an enzymatic reaction
E) binding of an ATP molecule along with one of the substrate molecules in an active site

Quizplus · Accepted Answer

Cooperativity is when binding of a molecule to one site on a protein or enzyme affects the binding properties of other sites on the same protein or enzyme. In this case, a molecule binding at one unit of a tetramer (a protein made up of four subunits) affects the binding properties of the other three units, indicating cooperativity. The other options do not involve cooperativity.
