Ch 8: Campbell Biology Chapter 8: An Introduction to Metabolism

About This Chapter

The Introduction to Metabolism chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with metabolism. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Introduction to Metabolism textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Introduction to Metabolism chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the metabolism 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:

  • Types of energy
  • Metabolic processes
  • Laws of thermodynamics
  • The significance of Gibbs free energy
  • How plants use energy from the sun
  • The importance of ATP
  • Different functions of enzymes
  • The process of allosteric regulation

Test your knowledge with a 30-question chapter practice test
What is Energy? - Definition and Significance in Nature

1. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Metabolism: Definition & Overview

2. Metabolism: Definition & Overview

Metabolism is the sum of all chemical reactions within the body. This concept, however, is much more complex than most of us understand. This lesson describes metabolism and the processes involved.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

3. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.

First Law of Thermodynamics: Law of Conservation of Energy

4. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

Second Law of Thermodynamics: Entropy and Systems

5. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

Gibbs Free Energy: Definition & Significance

6. Gibbs Free Energy: Definition & Significance

Have you ever wondered why some things just happen spontaneously? Have you ever asked yourself why salt dissolves in water? In this lesson, you will understand the meaning of the Gibbs free energy and how it helps us predict if a chemical reaction will happen spontaneously.

Energy and Life: The Transformation of Energy in Living Organisms

7. Energy and Life: The Transformation of Energy in Living Organisms

While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.

Muscle Metabolism: Synthesis of ATP

8. Muscle Metabolism: Synthesis of ATP

Did you know our muscles use billions of molecules every second to contract? This lesson describes the different metabolic processes by which ATP is generated by the muscle cell. Examples are utilized to define glycolysis, the citric acid cycle and oxidative phosphorylation.

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!

Allosteric Regulation & Feedback Inhibition of Enzymes

10. Allosteric Regulation & Feedback Inhibition of Enzymes

Like miniature factories, our cells are always working, and they want to avoid producing too much or too little. The solution is in enzyme regulation. In this lesson we will explore one type of enzyme regulation, and see exactly how this works.
