Question

which of the following is false about the structure of enzymes? a every enzyme has an active site. b an enzyme can catalyze most reactions if the reactants are at a high concentration. c an enzymes active site is determined by the shape of the enzyme. d enzymes speed up reaction rates.

Explanation:

Enzymes are highly specific in the reactions they catalyze due to the unique shape of their active - sites. They are not general - purpose catalysts that can work on most reactions even with high reactant concentrations. Every enzyme has an active site which is determined by its shape and they speed up reaction rates.

Answer:

B. An enzyme can catalyze most reactions if the reactants are at a high concentration.
