WebThe enzyme concentration is the limiting factor slowing the reaction. Enzyme concentration As the concentration of the enzyme is increased, the enzyme activity also increases. … WebEnzyme inhibitors are compounds which modify the catalytic properties of the enzyme and, therefore, slow down the reaction rate, or in some cases, even stop the catalysis. Such inhibitors work by blocking or distorting the active site. Enzyme inhibition can be categorized in three types: competitive, noncompetitive, and uncompetitive.

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.
