It presents the highest activity in organic media None of the answers C. d. All of the answers it is less used than Candida antarctica Lipase A Its active site has a nucleophilic serine residue Which of these statements is a disadvantage of enzymes in organic solvents? Elimination of microbial contamination b. Increased solubility of non-polar substrates and products, which speeds up overall reaction rates о Which of the following statements is true? Regioselectivity: Ability to form one specific isomer to a greater extent than the other Chemoselectivity; Ability to select a specific chemical method None of the statements is correct Stereoselectivity: Ability to act on one location in a molecule Suppression of unwanted water-dependent side reactions, which often degrade common organic reactants d. Mass transfer limitations in case of heterogeneous systems or viscous solvents Which of these is false regarding disadvantages of enzyme im nobilization? Substrate needs to diffuse through the gel/membrane Immobilisation can affect shape of active site so fewer enzyme-substrate complexes Enzymes might dettach from the support all answers are disadvantages of enzyme immobilization Enzyme is present at lower concentration when immobilised Which of these statements is true? Fluorinated solvents have low boiling points and can be handled at high pressures Hydrofluorocarbons have lower polarities than corresponding organic solvents Perfluorinated solvents have higher polarities than corresponding organic solvents Differences in polarity help overcome solubility issues for a wide range of substrates
