1. Most inhibitors work by preventing _____.
enzymes from working
products from forming
reactants from combining
combustion from occurring
To determine the correct answer to this question, let's analyze each option:
1. Enzymes from working: Enzymes are proteins that catalyze (speed up) chemical reactions. Inhibitors can indeed work by preventing enzymes from functioning properly, thus slowing down or stopping the chemical reactions they catalyze.
2. Products from forming: Products are the substances that are formed as a result of a chemical reaction. Inhibitors, however, do not typically prevent products from forming. Instead, inhibitors mainly affect the reactants or the enzymes involved in the reaction.
3. Reactants from combining: Reactants are the substances that undergo a chemical reaction to form products. Some inhibitors can indeed prevent reactants from combining properly, hindering the reaction from occurring.
4. Combustion from occurring: Combustion is a rapid chemical reaction that involves the reaction of a fuel with oxygen to produce heat and light. Inhibitors are not commonly used to prevent combustion from occurring; they are more commonly used in chemical reactions that involve enzymes.
Therefore, based on the options given, the correct answer is: most inhibitors work by preventing enzymes from working.
