Immobilized Enzyme
Which medium is used for the production of Penicillin using immobilized cells
Which of the following is not a physical method of immobilization?
Damkohler number(NDa) is
If Damkohler number, NDa >>1, the reaction rate is much greater than the mass transfer rate and the overall reaction is controlled by the rate of mass transfer. In this case, the enzyme reaction can be described as (where Csb and Cs are the substrate concentration in bulk of solution and at the immobilized enzyme surface respectively. ks mass transfer coefficient, and a is the surface area of an immobilized enzyme particles)
Which of the following is not the correct answer?

Commonly employed water insoluble supports for the covalent attachment of enzyme include
For a steady state condition, the change of substrate concentration (dCs/dt) is
To measure the extent to which the reaction rate is lowered because of resistance to mass transfer, the effectiveness factor of an immobilized enzyme, η can be defined as
