WebEnzymes and activation energy. A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that … WebThe effect of a catalyst on the activation energy is shown on a chart called a reaction profile. This shows how the energy of the reactants and products change during a reaction.
WebTerms in this set (60) A chemical reaction is when bonds are broken and formed. A nuclear reaction is when nuclei emit particles and/or rays. In a chemical reaction, atoms … WebEnzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules. Sort by: Top Voted Questions
