Ch 39: Metabolism in the Human Body

About This Chapter

In this overview of metabolism in the human body, you can review nucleic acids, enzymes, and hydrolysis reactions. The short lessons in this chapter can be a valuable tool to use when preparing for a test or working on class assignments.

Metabolism in the Human Body - Chapter Summary

With this chapter on metabolism in the human body, you can review the metabolism of fats, proteins, and carbohydrates. There is also a discussion that will help you understand why DNA is called the 'blueprint of life.' By the end of the chapter, you should feel confident and prepared to:

  • Explain how macronutrients are used in the body
  • Define and explain how enzymes work
  • Detail the structure and form of nucleic acids
  • Recall what causes denaturation of protein
  • List the chemical components of starch
  • Provide examples of different types of hydrolysis reactions
  • Discuss the function of coenzymes
  • Recount how energy-yielding nutrients work in your body

These engaging lessons and self-assessment quizzes can help you easily understand the topics presented. You can review all the lessons in order or just the ones covering topics in which a refresher would be helpful. The quizzes that accompany each lesson can also be printed and used as study worksheets.

The Metabolism of Fats, Proteins & Carbohydrates

1. The Metabolism of Fats, Proteins & Carbohydrates

Everybody eats. But what happens to that food once it is eaten? Cellular respiration explains carbohydrates, but what about fat and protein? This lesson explores how all three macronutrients are used by the body.

What are Enzymes? - Definition & Explanation

2. What are Enzymes? - Definition & Explanation

In this lesson, you will discover what enzymes are, explore how they work, and learn why they're needed for your cells' day-to-day functions. The lesson concludes with a quiz to test your knowledge.

Nucleic Acids: Function & Structure

3. Nucleic Acids: Function & Structure

In this lesson, we will explore what nucleic acids are, including the oozing bodily fluid they were first found in, what makes them unique from other types of biological molecules, and why DNA is called the 'blueprint of life.'

Denaturation of Protein: Definition & Causes

4. Denaturation of Protein: Definition & Causes

Proteins are found in all living organisms. Problems occur when proteins become denatured. In this lesson, you will learn about a change in proteins known as denaturation.

What is Starch? - Definition, Function & Chemical Formula

5. What is Starch? - Definition, Function & Chemical Formula

In this lesson, you'll learn what starch is composed of and some foods that contain it. In addition you will discover more about the chemical components of starch as well as its function inside and outside the body.

Hydrolysis: Definition, Reaction, Equation & Example

6. Hydrolysis: Definition, Reaction, Equation & Example

Have you ever wondered why the hydrolysis reaction is used to break table sugar, or sucrose, into glucose and fructose sugars? Continue reading to learn about the hydrolysis reaction, including examples of different types of hydrolysis reactions.

Coenzyme: Definition & Function

7. Coenzyme: Definition & Function

This lesson defines what a coenzyme is and how it relates to enzymes. It also discusses the functions of a coenzyme and gives some information as to where coenzymes can be found.

Energy-Yielding Nutrients: Carbohydrates, Fat & Protein

8. Energy-Yielding Nutrients: Carbohydrates, Fat & Protein

Carbohydrates, fats and proteins are referred to as the three energy-yielding nutrients because they provide your body with energy that is measured in calories. You'll also learn about another substance that can provide your body with calories, even though it is not a nutrient.
