Final answer:
Enzymes are not non-specific and can only catalyze specific reactions.
Step-by-step explanation:
B) False. Enzymes are highly specific catalysts that are usually made of amino acids. They function by lowering the activation energy of the reaction they are catalyzing, which can dramatically increase the rate of the reaction.
Each enzyme is only capable of speeding up one or a few very specific reactions or types of reactions.
