Enzymes Biochemistry Quiz: Trivia Test! - Quiz

Do you know anything about enzymes and biochemistry? Do you think you can pass this quiz? It is defined as a macromolecule that catalyzes a biochemical reaction. In this type of chemical reaction, the starting molecules are called substrates. The enzyme is responsible for many chemical functions such as digestion of food, providing cellular energy, supporting brain function, and repairing the body's healing processes. Take this quiz and learn more about enzymes.
