They are made inside cells. Most of them work inside the cell, but some (e.g. digestive enzymes) work outside the cell. Enzymes are biological catalysts. A catalyst speeds up a chemical reaction. It does not change the final products. A catalyst is not changed by the reaction – therefore it can be used over and over again.

Enzymes work the same way as catalysts do, they can work with only one substrate and they can be used more than once. Enzymes have a structure that is called active site. Only one substance can fit into the active site to be digested, and it is the only substrate that this particular enzyme works with. cheap slow cooker family meals

WebEnzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. WebEnzymes catalyze all aspects of cell metabolism. This includes the digestion of food, in which large nutrient molecules (such as proteins, carbohydrates, and fats) are broken down into smaller molecules; the conservation and transformation of chemical energy; and the construction of cellular macromolecules from smaller precursors.
