# Enzymes

**In this chapter, you will learn to:**

* Define enzymes and their nature.
* Describe how enzymes catalyze biochemical reactions.
* Examine the progression of reactions controlled by enzymes.
* Summarize how a colorimeter can be used to track enzyme-catalyzed reactions.
* Investigate and explain how factors such as temperature, pH, enzyme concentration, and substrate concentration influence the rate of enzyme activity.
* Utilize **Vmax** and **Km** values to compare how strongly different enzymes bind to their substrates.
* Explain how reversible inhibitors, including both competitive and non-competitive types, affect enzyme function.
* Identify the benefits of employing immobilized enzymes in various applications.
