Enzymes are an essential part of the functioning of the human body. They are made of proteins and have a number of unique functions depending on the active site and substrate.Substrate Binding to the Enzyme Active Site by Tim Vickers (CC0)Which of the following statements is NOT true regarding the function of an enzyme?Elimination ToolSelect one answerAEnzymes are specific to one or a few substrates based on their active site.BEnzymes are recycled and reused.CEnzymes are considered a reactant in a reaction.DEnzymes decrease the activation energy of a reaction.
