In an experiment, laboratory rats were classically conditioned to get sick after drinking sweetened water that was paired with a drug that compromises immune response. these rats continued to die after the experiment because of the conditioned response to the sweetened water alone. which conclusion can be drawn from this research?

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
