WebMost enzymes catalyse their reactions to a rate that is 1,000-10,000 times slower than this limit. This is due to both the chemical limitations of difficult reactions, and the evolutionary limitations that such high reaction rates do not confer any extra fitness. [1] History [ edit] WebJul 17, 2024 · Enzymes are specialized protein catalysts. In contrast to chemical catalysts, enzymes are often highly specific, and many enzymes catalyze a single reaction [ 4]. For example, carbonic anhydrase catalyzes the conversion of carbon dioxide and water to carbonate and protons.

WebIf an inhibitor is noncompetitive, the enzyme-catalyzed reaction will never reach its normal maximum rate even with a lot of substrate. This is because the enzyme molecules with the noncompetitive inhibitor bound are "poisoned" and can't do their job, regardless of how much substrate is available.
