Kuo-Chen Chou was the first to successfully explain enzymes with this property, which can have catalytic efficiencies on the order of ten to the tenth power inverse molar-seconds. For 10 points each:
[10h] Name this very rare property possessed by enzymes that catalyze vital time-sensitive reactions, such as acetylcholinesterase and superoxide dismutase.
ANSWER: diffusion-limited [prompt on catalytically perfect or kinetically perfect]
[10e] The most famous diffusion-limited enzyme is this generically-named enzyme that decomposes hydrogen peroxide to water and oxygen.
ANSWER: catalase
[10m] This diffusion-limited enzyme maintains the blood pH buffering system by strictly controlling the blood’s concentration of bicarbonate ions.
ANSWER: carbonic anhydrase [or carbonate dehydratase]
