Which of the following is NOT true about enzymes?
Enzymes are complex nitrogenous organic compounds
Enzymes are produced by living plants and animals
Enzymes form crystalline solutions in water
Enzymes catalyze numerous reactions in natural processes
Enzymes are complex nitrogenous organic compounds that are produced by living plants and animals. They form colloidal solutions in water. Enzymes are very effective catalysts and catalyze numerous reactions in natural processes. Enzymes lower the activation energy needed for a chemical reaction to occur, making reactions more efficient and increasing the rate of reaction.
The statement that enzymes form crystalline solutions in water is incorrect. Enzymes form colloidal solutions in water. While some enzymes have been obtained in pure crystalline form for structural studies, this is not true for all enzymes.
