Unlike hydrogen, which is often abstracted from substrates as H⁺, electronegative ____ cannot be readily eliminated as ____, thus enzyme inhibitors can be fashioned in which ____ replaces H at positions where catalysis involves H-removal as H⁺. A) sodium; Na⁺; Na B) potassium; K⁺; K C) deuterium; D⁺; D D) fluorine; F⁺; F E) all are true

Question

Quizplus · Accepted Answer

Electronegative fluorine cannot be readily eliminated as F⁺, thus enzyme inhibitors can be fashioned in which F replaces H at positions where catalysis involves H-removal as H⁺. Options A (sodium) and B (potassium) are not electronegative, and option C (deuterium) is a stable isotope of hydrogen and not an electronegative element.
