Enzyme Quizzes & Trivia

Enzymes are biological molecules which are made from amino acids, and they are proteins, that speed up the rate of virtually all of the chemical reactions that take place within cells. This quiz deals with functions and properties of enzymes. So, let's try out the quiz and increase your knowledge. All the best!
