Ch 3: Holt McDougal Modern Biology Chapter 3: Biochemistry

About This Chapter

The Biochemistry chapter of this Holt McDougal Modern Biology textbook companion course helps students learn essential modern biology lessons on biochemistry. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Biochemistry textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Modern Biology Biochemistry chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the biochemistry 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:

  • Functional groups of organic molecules
  • Monomers and polymers
  • Hydrolysis and dehydration
  • The relationship between energy-containing molecules and physical activity
  • Major elements of biological molecules
  • Structure and function of carbohydrates
  • Structure and function of lipids
  • Structure and function of proteins
  • Function of enzymes

Introduction to Organic Molecules I: Functional Groups

1. Introduction to Organic Molecules I: Functional Groups

If you've ever wondered what gives vinegar that sour flavor, you may not realize that you have contemplated functional groups. View this lesson for an introduction to organic chemistry, functional groups and how they are part of your daily life.

Introduction to Organic Molecules II: Monomers and Polymers

2. Introduction to Organic Molecules II: Monomers and Polymers

From everyday man-made items like milk jugs and styrofoam to natural proteins and plant materials, the world is full of polymers! Check out this lesson to learn how polymers are constructed on a molecular level.

Hydrolysis and Dehydration: Definitions & Examples

3. Hydrolysis and Dehydration: Definitions & Examples

Water is an important component of cellular processes. Two of these processes, dehydration and hydrolysis, help your body build large molecules from small ones and break down large ones into usable components.

How Energy-Containing Molecules Support Physical Activity

4. How Energy-Containing Molecules Support Physical Activity

Physical activity requires energy. Adenosine triphosphate (ATP) is the form of energy your body likes to use. In order to keep enjoying your physical activity, your body must continually make ATP. Learn how this is done both with and without oxygen.

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

5. 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.

Structure and Function of Carbohydrates

6. 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

7. 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

8. 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.

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!
