What term describes enzymes that are attached or fixed to each other or to an inert material?

Explanation:
Immobilising enzymes means attaching them to a solid support or fixing them in a matrix. This keeps the enzyme in place so it can be reused in processes, and makes it easier to separate from the reaction mixture, often improving stability and allowing continuous operation. The term describes enzymes that are attached or fixed to an inert material. A general enzyme isn’t necessarily fixed in place; a denatured enzyme has lost its activity, and a protease is simply a type of enzyme that digests proteins, not a description of immobilisation.
