Correct choice is (a) True
The explanation: Immobilized enzyme systems offer cost advantages to users in terms of total manufacturing costs. Also, the plant size needed for continuous processes is two orders lesser magnitude as compared to batch processes using free enzymes. As a result, the capital costs considerably smaller and the plant may be prefabricated cheaply off-site. Immobilised enzymes offer greatly increased productivity on an enzyme weight basis and also often provide process advantages. Hence the above statement is true.
