Ch 3: Inorganic and Organic Chemistry for High School Biology

About This Chapter

The lessons in this chapter provide you with a quick review of inorganic and organic chemistry topics related to biology. Key topics include atomic structure, chemical bonds, properties of water and other molecular structures.

Inorganic and Organic Chemistry for High School Biology - Chapter Summary

With the exception of subatomic particles, nearly everything is made up of atoms, including inorganic and organic molecules. The lessons in this chapter provide you with a way to reinforce your understanding of atomic elements, as well as how these elements form chemical bonds to create different molecules and organic compounds. These inorganic and organic chemistry topics provide building blocks to the study of biology. Study these lessons to improve your knowledge regarding:

  • What the structures of an atom are
  • How various chemical bonds function
  • Properties of water and why they are important
  • What redox reactions are
  • How carbohydrates are structured and their functions
  • What the structures and functions of lipids are
  • The structures of proteins and why they are important

9 Lessons in Chapter 3: Inorganic and Organic Chemistry for High School Biology
The Atom

1. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

The Electron Shell

2. The Electron Shell

You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?

Overview of Chemical Bonds

3. Overview of Chemical Bonds

Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.

Chemical Bonds IV: Hydrogen

4. Chemical Bonds IV: Hydrogen

This lesson is going to define and discuss for you important concepts behind hydrogen bonding. You'll learn when and why these bond occurs and which atoms are often involved.

Properties of Water

5. Properties of Water

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

6. Redox (Oxidation-Reduction) Reactions: Definitions and Examples

This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.

Structure and Function of Carbohydrates

7. Structure and Function of Carbohydrates

Carbohydrates are found in many foods that we eat and may be found as sugars, starches, or fiber. Learn more about these three distinct types of carbohydrates, and how they are distinguished through their chemical structures in this lesson.

Structure and Function of Lipids

8. Structure and Function of Lipids

Molecules called lipids have long hydrocarbon chains that determine the way they act. They can be fats, oils, or hormones, and even exist in our cell membranes. Learn more about the chemical structure and biological function of various lipids in this lesson.

Proteins I: Structure and Function

9. Proteins I: Structure and Function

We need our proteins, not just as a major food group but for the many useful roles that they play in our bodies. In our introductory lesson to proteins, you'll learn about the many functions we rely on them to perform.
