WebCatalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions. Common types of catalysts include enzymes, acid-base catalysts, and heterogeneous … WebA catalyst increases the rate of the reaction because: They provide an alternative energy pathway that has a lower activation energy This means that more particles have the activation energy required for the reaction to take place (compared to without the catalyst) and so the speed of the reaction increases Answered by Vanessa O.•Chemistrytutor
WebEnzymes are defined as catalysts that speed up chemical reactions but remain the same themselves. The shape of an enzyme enables it to receive one type of molecule and that specific molecule will fit into the enzyme’s shape. Where a substance fits into an enzyme is called the active site and the substance that fits into the active site is ...
