A molecule that binds at the active site of an enzyme and so stops the natural substrate from attaching is called
Aa non-competitive inhibitor
Ba competitive inhibitor
Can allosteric activator
Da coenzyme that speeds up the reaction
Answer: B
Enzyme activity needs the substrate to occupy the active site. A molecule that sits in that same site and keeps the substrate out is a competitive inhibitor. A non-competitive (allosteric) inhibitor binds elsewhere.
