Ch 2: Prentice Hall Biology Chapter 2: The Chemistry of Life

About This Chapter

The Chemistry of Life chapter of this Prentice Hall Biology Companion Course helps students learn essential biology lessons on the chemistry of life. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Chemistry of Life textbook chapter.

How it works:

  • Identify the lessons in the Prentice Hall Chemistry of Life chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the chemistry of life topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The atom
  • Covalent and ionic bonds
  • Water properties
  • Acids and bases
  • Proteins, nucleic acids, lipids and carbohydrates
  • Structure and function of proteins
  • Biochemical reactions
  • Enzyme functions

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?

Chemical Bonds I: Covalent

2. Chemical Bonds I: Covalent

Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.

Chemical Bonds II: Ionic

3. Chemical Bonds II: Ionic

Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.

Properties of Water

4. 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.

Acids and Bases

5. Acids and Bases

Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.

Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

6. Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

Bacterial cells have complex macromolecules built from simple molecules. In this lesson, we will look at the major elements in the building blocks of proteins, nucleic acids, carbohydrates, and lipids.

Proteins I: Structure and Function

7. 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.

Biochemical Reactions: Synthesis and Decomposition

8. Biochemical Reactions: Synthesis and Decomposition

Did you know that there are thousands of chemical reactions going on in your body every day? In this lesson, you will learn about three types of biochemical reactions: synthesis reactions, decomposition reactions and reversible reactions.

Function of Enzymes: Substrate, Active Site & Activation Energy

9. Function of Enzymes: Substrate, Active Site & Activation Energy

In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!
