7. Enzyme Inhibition and Regulation

L-arginine is capable of binding to and activating N-acetylglutamate synthase. Since L-arginine is neither a substrate nor a product of this enzyme, how would this effector be classified?

Considering that O₂ triggers hemoglobin to switch from its low affinity (T) state to its high affinity (R) state to bind more O₂, what kind of allosteric effector is O ₂ relative to hemoglobin?

Which of the following statements about allosteric control of enzymatic activity is false?
