About This Chapter
GRE Biology: Inorganic Chemistry Review - Chapter Summary
Brush up on chemical bonding, solution chemistry and chemical reaction basics to prepare for the GRE Biology exam. The entertaining video lessons included in this chapter can help you review the following topics:
- Cellular molecules, macrominerals, and trace elements
- Covalent, ionic, polar covalent, and hydrogen bonds
- Properties of ice and liquid water
- Solutions, solutes, and solvents
- Saturation, osmosis, and diffusion
- Acids, bases, and solution pH
- Oxidation-reduction reactions
- Hydrolysis and dehydration reactions
- Anabolism and catabolism
The video lessons and transcripts found in this chapter are accessible through a modular course format that allows you to take on as many topics at a time as you'd like. There are also self-checking lesson quizzes and a chapter test useful for determining how much more study time you need to put in. Plus, our experienced instructors are available to answer any questions you might have about inorganic chemistry.
GRE Biology Objectives
GRE subject tests are used to gauge the academic preparedness of applicants to graduate degree programs. If biology is a subject area where you excel, you might consider submitting GRE Biology test scores to supplement your other application materials.
The test itself contains around 190 multiple-choice questions covering three main content domains. The videos and quizzes included in this chapter can help you review the inorganic chemistry concepts you'll need to successfully answer questions found in each of the exam's cellular and molecular biology, organismal biology, and ecology and evolution sections.
1. The Foundational Elements of Life
Living things are complex products of their environments. They are made of a number of different natural elements, many of which are essential to survival. Because of this, they are considered foundational elements and they support life on Earth as we know it.
2. Chemical Bonds I: Covalent
Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.
3. Chemical Bonds II: Ionic
Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.
4. Chemical Bonds III: Polar Covalent
Are you confused about how you can tell what kind of bond two atoms will form? This lesson will help you understand the difference between polar and nonpolar covalent bonds as well as how to predict how two atoms will interact.
5. Chemical Bonds IV: Hydrogen
This lesson defines and discusses important concepts behind hydrogen bonding. You'll learn when and why these bonds occur and which atoms are often involved.
6. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
7. Solutions, Solutes, and Solvents
Solutions, solutes, and solvents are terms that are frequently thrown around in chemistry. Find out what these terms mean and learn why certain substances form solutions.
8. Osmosis, Diffusion and Saturation
The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.
9. Acids and Bases
Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.
10. Basic Properties of Chemical Reactions
Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.
11. Redox (Oxidation-Reduction) Reactions: Definitions and Examples
This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.
12. 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.
13. What Are Ionic Compounds? - Definition, Examples & Reactions
Ionic compounds are a common, yet special type of chemical compound. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions.
14. Anabolism and Catabolism: Definitions & Examples
Metabolism breaks down large molecules like food into usable energy. This energy drives bodily processes critical to survival. In this video lesson, you will learn about the two forms of metabolism that break down and build up molecules and see examples of each.
15. Weak Acids, Weak Bases, and Buffers
This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.
