WebApr 8, 2024 · Owing to their extraordinary catalytic functions and relatively high substrate specificity, enzymes have been frequently used as key components for the construction of practical, enzyme-based biosensors for the sensing or detection of target analytes in complex biological systems . Over the past few decades, biochemists have devoted … WebEnzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently. shmeky twitter

Enzyme Specificity. Answer to Question #3. C is correct. In all enzymes, there is only one direction: from substrate to product. Once the product is created, the enzyme to longer recognizes the molecule, because it is specific to the substrate it is intended to act up. If enzymes could work both ways, nothing would ever get done …

WebEnzymes have usually evolved to catalyze one reaction, or a particular class of reaction, and the level of specificity will depend on the function of the particular enzyme. In some cases, enzymes will act on a broad range of substrates, just as nature intended. Examples of the latter type of enzymes are the cytochromes P-450 and the glutathione ...
