WebSep 10, 2024 · How do activators affect enzymes? Enzyme activators are molecules that bind to enzymes and increase their activity. They are the opposite of enzyme inhibitors. These molecules are often involved in the allosteric regulation of enzymes in the control of metabolism. What are activators and enhancers? WebEnzymes are really not consumed in a reaction but they also 'age' overtime as proteins normally do and undergo ubiquitination. Thus, new enzymes are needed when these enzymes 'age'. Also take note that enzymes are well regulated thus when there is a surmounting amount of it, the body reacts via negative feedback and inhibits its formation.
