Ch 11: GED Science - Biomolecules: Help and Review

About This Chapter

The Biomolecules chapter of this GED Science Help and Review course is the simplest way to learn about biomolecules. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of biomolecules.

Who's it for?

Anyone who needs help learning or mastering GED science material will benefit from taking this course. There is no faster or easier way to learn GED science. Among those who would benefit are:

  • Students who have fallen behind in understanding DNA or organic molecules
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about biomolecules
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the biomolecules chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the biomolecules chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any biomolecules question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a biomolecules unit of a standard GED science course. Topics covered include:

  • Functional groups in organic molecules
  • Monomers and polymers in organic molecules
  • Structure and function of lipids, carbohydrates and proteins
  • Structure of DNA
  • Differences between DNA and RNA

14 Lessons in Chapter 11: GED Science - Biomolecules: Help and Review
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.

Structure and Function of Carbohydrates

3. 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

4. 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

5. 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.

Proteins II: Amino Acids, Polymerization and Peptide Bonds

6. Proteins II: Amino Acids, Polymerization and Peptide Bonds

In this lesson, we'll take a deeper look at amino acids. You'll learn what makes a peptide, and what separates a protein from other kinds of amino acid bonds.

DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

7. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

In this lesson, you'll discover what nucleotides look like and how they come together to form polynucleotides. We'll also explore nucleic acids and focus on DNA in particular.

DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing

8. DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing

Learn the language of nucleotides as we look at the nitrogenous bases adenine, guanine, cytosine and thymine. Armed with this knowledge, you'll also see why DNA strands must run in opposite directions.

DNA: Discovery, Facts, Structure & Function in Heredity

9. DNA: Discovery, Facts, Structure & Function in Heredity

This lesson will help you to navigate the twists and turns of DNA's structure. We'll also clue you in on the amazing discoveries that put this nucleic acid in the limelight as the molecule of heredity.

Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

10. Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

In this lesson, you'll explore RNA structure and learn the central dogma of molecular biology. Along the way, you'll meet the three types of RNA and see how the cell uses them most effectively.

Endotoxins: Definition & Examples

11. Endotoxins: Definition & Examples

Let's investigate the potentially deadly endotoxins. Endotoxins are a substance unique to gram-negative bacteria. Uncover how our immune system copes with endotoxins and their associated health effects in this lesson.

Enzyme Rate of Reaction: Factors & Catalysts

12. Enzyme Rate of Reaction: Factors & Catalysts

What is an enzyme? Why are they important? How can they change? This lesson answers those questions. It teaches us how enzymes work and how they can be changed. It also includes illustrations, examples, and a brief quiz.

Pyruvate Oxidation: Products & Overview

13. Pyruvate Oxidation: Products & Overview

During one phase of aerobic respiration, pyruvate is oxidized in order to release energy. This lesson will discuss the various processes required to break down pyruvate and the resulting products that are formed.

What Are Digestive Enzymes? - Functions & Types

14. What Are Digestive Enzymes? - Functions & Types

We are what we eat. But that doesn't mean our blood vessels are filled with giant chunks of hamburger. Thankfully, digestive enzymes help break down food into sizes small enough to be absorbed into our bloodstream. In this lesson, learn about these vitally important proteins.
