WebEnzymes need to exert some force to catalyze a reaction and they do that through ionic and/or hydrogen bonding. If all enzymes did was float around and look disapprovingly at their substrates, they wouldn't be very effective. 2 comments ( 16 votes) Upvote Downvote Flag more Show more... Laura.Ramirez.2014 8 years ago at 3:52 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

WebIn fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. Thus, noncompetitive inhibition acts by reducing the number of functional enzyme molecules that can carry out a reaction. grand island nebr weather
