About This Chapter
OAE Biology: Biochemistry - Chapter Summary
Our biochemistry video lessons will help you understand the chemical processes of living organisms. The lessons in this chapter will introduce you to key concepts and terms in the field of biochemistry. After studying this guide, you will be able to:
- Differentiate between synthesis and decomposition
- Discuss the different functions of enzymes
- Understand the functions and interactions of coenzymes, cofactors & prosthetic groups
- Distinguish between inhibition and regulation enzymatic reactions
- Define redox reactions & electron carriers in cellular respiration
- Articulate the importance and processes of the glycolysis pathway
- Comprehend the citric acid (krebs) cycle
- Explain how a phospholipid bilayer is both hydrophobic and hydrophilic
Instructors have organized these video lessons to explain basic concepts of biochemistry in a simple, effective way. Learn to tell apart your regulation enzymatic reactions from your inhibition reactions, and then, when you think you understand the chapter, see how you fare against our self-assessments.
OAE Biology: Biochemistry Chapter Objectives
Passing the Ohio Assessments for Educators (OAE) is required for anyone seeking employment as a teacher in the state of Ohio. Teachers must pass the OAE corresponding to the subjects they wish to teach. Instructors teaching 7th grade through 12th grade life sciences must pass the Biology OAE exam. To pass, one must earn a score of 220 on a scale of 100 to 300. Questions are derived from a set of standards determined by the state of Ohio.
The Biology OAE consists of five domains, including one focused on biochemistry and cell biology. This section accounts for 13% of the questions on the Biology OAE exam. This study guide will get you comfortable with subject matter that may pop up on this section of the test. The computer-based Biology OAE exam consists of 150 questions and has a three-hour time limit. All questions are stand-alone and multiple-choice.
1. Biochemical Reactions: Synthesis and Decomposition
Did you know that there are thousands of chemical reactions going on in your body every day? In this lesson, you will learn about three types of biochemical reactions: synthesis reactions, decomposition reactions and reversible reactions.
2. 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!
3. Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions
Some enzymes require helpers to recognize a substrate or complete a reaction. These helpers include cofactors, coenzymes, and prosthetic groups, which are required for some enzymes' functions.
4. Enzymatic Reactions: Inhibition and Regulation
Enzymes are generally not allowed to run uncontrolled in a cell. While they are useful in catalyzing reactions, there is a time and place for everything. In this lesson, we'll discuss enzyme activators and inhibitors that regulate these reactions positively and negatively, respectively.
5. Redox Reactions & Electron Carriers in Cellular Respiration: Definitions and Examples
Redox reactions play an important role in cellular respiration. In this lesson, you will see how NAD and FAD are used as electron carriers to temporarily store energy during cellular respiration.
6. Glycolysis Pathway: Steps, Products & Importance
Cellular respiration creates chemical energy in the form of ATP from the food we eat and the air we breathe. In this lesson, we'll learn about the first part of this process, glycolysis.
7. The Citric Acid (Krebs) Cycle: Products and Steps
In this lesson, we return to the process of cellular respiration for the second act of creating energy from food. In this act, products from glycolysis feed into the next stage, the citric acid cycle.
8. How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic
In this lesson, we will learn what gives phospholipids a dual personality. How can this molecule be both hydrophobic and hydrophilic, and why is this important to a cell?
