Chemical models of enzymes
WebA laboratory experiment is described in which students carry out immobilization of the enzyme invertase via entrapment in alginate (Ca-alginate) and, accordingly, estimate values for kinetic constants and mass transfer coefficients. Immobilization of enzymes, or confinement thereof to a defined space with retention of most catalytic activity, is … Weba) an enzyme provides a reactions surface and a suitable environment of the reactions to take place b) an enzyme binds reactants such that they are positioned correctly and can attain their transition state configurations c) an enzyme allows the reaction to go through a less stable transition state that would normally be the case
