About This Chapter

Brush up on your knowledge of biomolecules and cells as part of your review for the AGPQT exam. Use these videos and text lessons to prepare for biology questions on this exam.

AFOQT: Biomolecules & Cells - Chapter Summary

Use these lessons to learn about the structure and function of biomolecules and cells as you review for the Air Force Officer Qualifying Test. You can also practice answering questions that reflect the format of the questions on the AFOQT. After completing this lesson, you should be able to answer questions about the following:

  • Structure & function of carbohydrates, proteins and lipids
  • DNA composition and structure
  • Cells
  • Nucleus structure
  • Ribosomes
  • Chromosome structure

The instructors help you prepare for biomolecule and cell questions by reviewing the content in a concise way without compromising the integrity of the content. The lessons are either composed of short videos or texts with accompanying assessments to help check your learning as you complete the lessons. The personal dashboard is a feature that can be used to track your overall progress.

Structure and Function of Carbohydrates

1. 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

2. 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

3. 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.

DNA: Discovery, Facts, Structure & Function in Heredity

4. 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.

What are Cells? - Overview

5. What are Cells? - Overview

All living organisms are made up of cells, but do you know what a cell is? In this lesson, you can learn about the three main structures that all cells contain and about the two major types of cells.

Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores

6. Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores

In this lesson, we'll discuss the organization and importance of the nucleus in your cells. This is the membrane-bound structure responsible for containing all the genetic material essential to making you who you are.

Basic Genetics: The Genome & Chromosomes

7. Basic Genetics: The Genome & Chromosomes

There are approximately 3 billion bases in the human genome. In this lesson, you'll learn more about the genome and its organization into chromosomes. We think about DNA often as the blueprint for life, but we can also think of it as the recipe for life with the nucleus being the library.

How is DNA Organized into Chromosomes? - Structure & Function

8. How is DNA Organized into Chromosomes? - Structure & Function

Explore the structure of chromosomes and see how DNA fits inside the nucleus of the cell. In this lesson, you'll learn about histones, chromatin and nucleosomes.
