Did you know?

An immobilized enzyme is an enzyme, with restricted mobility, 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. It also lets enzymes be held in place throughout the reaction, foll… Witrynaof the nature of enzymes, the mechanism of enzyme action, and factors that affect the rate of enzyme-controlled reactions.
