    Enzymes are the protein substances, which serve the role of catalyzing the ________ reaction.

    Correct Answer
    biochemical
    Explanation
    Enzymes are protein substances that serve the role of catalyzing biochemical reactions. They act as biological catalysts, speeding up the rate of chemical reactions in living organisms. Enzymes are highly specific, meaning they can only catalyze a particular reaction or a group of closely related reactions. They do this by binding to the reactant molecules, called substrates, and facilitating the conversion of these substrates into products. Without enzymes, many biochemical reactions would occur too slowly to sustain life. Therefore, enzymes play a crucial role in various metabolic processes and are essential for the functioning of living organisms.
