Amount of product formed per time(in the case of catalase it's foam produced per minute which is a measure of the amount of oxygen formed per minute. |
|
Immobilized enzyme |
Enzyme that is fixed in position made insoluble and unable to move |

Uses of immobilized enzymes |
-food industry (pectins in juices released which changes colour and flavours) -chemical industry (proteases in washing powders) -production of antibiotics(penicillin acylase) |
