CONNECTION TO CHAPTER 2: chapter 3, chapter 4, chapter 5 eXPLANANTION: CHAPTER 3Atoms and elements from Chapter 2 combine to form the macromolecules that Chapter 3 focuses on.Chemistry explains how molecules like carbs, proteins, and lipids are built, which are essential for life. CHAPTER 4 Molecules from Chapter 2 make up the structures inside cells described in Chapter 4. Cells are built from chemical elements and compounds, so understanding chemistry helps explain cell structure. CHAPTER 5: Chemical reactions from Chapter 2 provide the energy and materials cells use to function. Cells perform work using energy released or stored in chemical bonds, so chemistry is the foundation for cellular processes.
