How do enzymes work gcse biology
WebSome enzymes can process 100s or 1000s of substrates per second. Enzymes are biological catalysts that work in cells, so they randomly move about wherever they are in … WebEnzymes function to reduce the activation energy required for a chemical reaction to occur. First, the enzyme binds to the substrate and slightly distorts its shape. The change in shape activates the substrate molecule and decreases the total activation energy required for the substrate to be turned into product.

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. WebMany enzymes work fastest in neutral conditions. Making the solution more acidic or alkaline will slow the reaction down. At extremes of pH the reaction will stop altogether. …
