What you need to learn in this chapter
In this chapter, we will learn about metabolism and enzymes. Metabolism refers to all the chemical reactions that occur in our body to maintain life. Enzymes, on the other hand, are special proteins that speed up these chemical reactions. We will learn about the naming of enzymes, which usually ends with "ase" and are derived from their substrates. We will also study the general properties of enzymes. Lastly, we will explore the application of enzymes in our daily lives, such as in digestion, laundry detergents, and food production.
