Which of the following best describes a characteristic of a reversible enzyme inhibitor? a) The inhibitor will temporarily bind to the enzyme during which time the substrate cannot be converted to product. b) The inhibitor binds tightly to the enzyme via non-covalent bonds and can dissociate from the active site. c) The inhibitor will covalently bind to the enzyme via a non-hydrolysable bond. d) The inhibitor will permanently alter the enzyme and the enzyme can no longer catalyze the conversion of substrate to product.

Transition-state inhibitors form extremely stable covalent bonds with the enzyme transition state complex are highly reactive and typically decompose within picoseconds bind at a site other than the active site are stable compounds that mimic stereo-electronic features of the transition state None of the above
3) Irreversible inhibitors of enzymatic reactions * bind to the enzyme only at low temperatures. affect only serine side chains. react with the enzyme (often covalently) to reduce the activity without being able to regenerate that activity. are bound to the enzyme by the lock-and-key mechanism and can enhance the activity. 4) A noncompetitive inhibitor * binds to the enzyme at a site other than the active site is always structurally similar to the substrate can be overcome by increasing the substrate concentration increases the value of the Michaelis-Mentin constant
