I think the pervasive idea that it's a childhood disorder is arbitrary. That's not how biology works. Focus and concentration are pretty static.. In fact, an estimated 2.6 million adults were prescribed ADD meds in 2012, nearly 25% of whom are between the ages of 26 and 34.
An immobilized enzyme is an enzyme that is attached to an inert, insoluble material such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride).This can provide increased resistance to changes in conditions such as pH or temperature. Economy: The immobilized enzyme is easily removed from the reaction making it easy to recycle the biocatalyst. 2  This is particularly useful in processes such as the production of Lactose Free Milk, as the milk can be drained from a container leaving the enzyme (Lactase) inside ready for the next batch.
induced enzyme (inducible enzyme) one whose production requires or is stimulated by a specific small molecule, the inducer, which is the substrate of the enzyme or a compound structurally related to it.
