Final answer:
The false statement regarding enzymes is that enzymes create reactions. Enzymes are catalysts that accelerate biochemical reactions but do not initiate them. They lower the activation energy, allowing reactions to occur more readily.
Step-by-step explanation:
The statement that is false regarding enzymes is that enzymes create reactions. Enzymes are biological catalysts that work by lowering the activation energy of a reaction, thereby speeding up the reaction rates. They are highly efficient and can catalyze up to several million reactions per second. However, enzymes do not create biochemical reactions; they only facilitate the reactions that are already possible based on the reactants' chemical makeup.
For example, a molecule of the enzyme carbonic anhydrase can catalyze about one million molecules in one second in human blood. Despite their efficiency, it is important to understand that enzymes do not change the thermodynamics of reactions; they do not change endergonic reactions (reactions that absorb energy) into exergonic reactions (reactions that release energy). Their role is simply to make biochemical reactions proceed at a faster rate than they would without the presence of the enzyme.
