- Biochemical reactions
- Enzyme functions
- Coenzymes, cofactors, and prosthetic groups
- Enzymatic reactions
- Redox reactions and electron carriers in cellular respiration
- Cellular respiration
- Glycolysis pathway
- The Citric Acid (Krebs) Cycle
Our informative instructors go over the basic aspects of biochemistry in preparation for the test. Having several different approaches gives you multiple ways of absorbing the material which makes learning efficient and fun.
Objectives of the MTEL Biology: Overview of Biochemistry Chapter
The MTEL Biology Exam is a comprehensive exam that evaluates your knowledge and understanding of all aspects of the field of biology. A passing grade on the exam is required to become a licensed biology educator in the Commonwealth of Massachusetts. The topics in the Overview of Biochemistry chapter are part of the Chemistry of Life and Cell Biology Objective of the exam which accounts for 14% of the questions. By taking the self-assessment quizzes that come with each video lesson you can check on your level of knowledge and get a good idea of the kinds of questions that will be on the exam.
The MTEL Biology Exam is a computer-based-test (CBT) consisting of 100 multiple-choice items and 2 open-response items. The multiple-choice portion will present you with a passage or question followed by several possible answers, only one of which is correct. The open-response items will evaluate your ability to integrate your knowledge in an analysis of two topics in essay form. The multiple-choice section counts for 80% of your grade, and the open-response section for 20%.
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. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
7. 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.
8. 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.
