WebJan 22, 2024 · In order to understand activation energy, we must first understand what energy is. Energy is the ability to do work. It comes in many forms, such as heat, light, chemical energy, and electrical energy. All of these forms of energy can be converted into each other.The activation energy of a reaction... WebEnzymes lower the activation energy of the reaction but do not change the free energy of the reaction. A substance that helps a chemical reaction to occur is called a catalyst, and the molecules that catalyze biochemical reactions are called enzymes. edlinkconnectionsWebEnzymes 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. edlink application

"WebJul 4, 2024 · A certain amount of energy contained in the molecules is required when the two molecules react together to form a product. If the two molecules do not have enough energy to react, then no product is produced. By lowering the activation energy, a catalyst allows the molecules to gain sufficient energy to overcome the barrier and form products. " - How do enzymes alter activation energy
