“9th Class Biology Chapter 6 Quiz: Enzymes” is one of the most important topics; it deals with enzymes as biological catalysts essential for carrying on life. This chapter is important for MDCAT aspirants because it helps them understand how biochemical reactions and their regulations are crucial areas often tested in exams. Our MDCAT Quiz for this chapter is designed to help you strengthen your understanding of these core concepts and do better in the exam.
Enzymes are proteins that have a special quality: they can catalyze biochemical reactions without undergoing any permanent changes themselves. In this chapter, students will be able to understand the unique characteristics of enzymes, including enzyme specificity and the model lock-and-key of their mechanism. Students will also study the factors affecting enzyme activity—temperature, pH, and substrate concentration—and come to know about the critical role of cofactors and inhibitors in the regulation of enzymatic functions. The concepts relate to real-life processes such as digestion and cellular respiration, connecting theory with practical applications.

What is the function of the induced fit model in enzyme-substrate interactions?
The enzyme changes shape to better accommodate the substrate
What is the term for the specific three-dimensional shape of an enzyme's active site?
Tertiary structure
Which type of enzyme inhibition involves a molecule binding to an allosteric site, changing the enzyme's shape?
Allosteric inhibition
What is the term for the process where an enzyme loses its shape and function due to a change in pH?
Denaturation
What is the effect of substrate concentration on enzyme activity?
Initially increases, then levels off
Which type of inhibition involves a molecule binding to the active site, preventing substrate binding?
Competitive inhibition
What is the role of an allosteric site on an enzyme?
A site other than the active site that can regulate enzyme activity
What is the effect of pH on enzyme activity?
It can denature the enzyme if outside the optimal pH range
What is the function of coenzymes in enzymatic reactions?
Assist enzymes by transferring chemical groups
What is the term for the process where an enzyme loses its shape and function due to extreme pH or temperature?
Denaturation
What is the term for the initial investment of energy required to start a chemical reaction?
Activation energy
