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 enzyme’s active site is determined by the shape of the enzyme.

D. Enzymes speed up reaction rates.

The false statement about an enzyme is; "an enzyme can catalyze most reactions if the reactants are at a high concentration.

Enzymes are biochemical catalysts which catalyze specific reactions in the body.

Enzymes function on the bases of a lock and key model. Enzymes have active sites that look exactly like their substrates  such that the enzymes fits exactly into its substrate as a lock fits a key.

Enzymes are highly specific so it is false to say that an enzyme can catalyze most reactions if the reactants are at a high concentration.
