Final answer:
False. Enzymes are specific to certain reactions and typically catalyze reactions in one direction. Some reactions controlled by reversible reactions may have two different enzymes, one for each direction, to prevent equilibrium and stall the reaction.
Step-by-step explanation:
True/False: Any enzyme can catalyze chemical reactions in both directions without being altered themselves.
False. Enzymes are catalysts in biochemical reactions and can increase the rate of reaction by binding with the reactants and properly orienting them. However, enzymes are specific to certain reactions and typically catalyze reactions in one direction. Some reactions controlled by reversible reactions may have two different enzymes, one for each direction, to prevent equilibrium and stall the reaction.
