Right choice is (d) The specificity of substrate binding is mediated by spatial arrangement of atoms in an enzyme’s substrate binding site as well as substrate.
The best explanation: Following are the properties which a biosensor should possess:
• If the biosensor used in invasive, the probe must be tiny and biocompatible, having no toxic or antigenic effects.
• The biosensor should be cheap, small, portable and capable of being used by semi-skilled operators.
• If the traditional methods used is encouraged and the decentralization of laboratory testing is discouraged, then there is no use of producing more biosensors. Thus, there should be a market for the biosensor.
“The specificity of substrate binding is mediated by spatial arrangement of atoms in an enzyme’s substrate binding site as well as substrate.” This is a property of active site of the enzyme.
