About This Chapter
Chemical Reactions of Metabolism - Chapter Summary
The lessons in this chapter review a variety of biological processes and help prospective middle school teachers in Florida prepare for the Florida Teacher Certification Exam Middle Grades General Sciences. After completing the lessons in this chapter you will have reviewed:
- The Calvin-Benson Cycle
- Photolysis and light reactions
- The process of plant respiration
- Electron Transport Chain
- The Krebs cycle
- The role of chlorophyll
- Lactic acid v. alcoholic fermentation
- Energy transfer in cells
- The pathway of glycolysis
- Redox reactions and electron carriers in cellular respiration
Each lesson contains a video or text prepared by professional educators to provide helpful information you can easily retain. A transcript of the video is included for easy reference to text information. Take the self-assessment quizzes at the end of each lesson to test your knowledge of the material covered.
Chemical Reactions of Metabolism - Objectives
The lessons in this chapter give an in-depth review of the biological processes that may be covered on the Florida Teacher Certification Exam for Middle Grades General Sciences. This exam is designed to evaluate potential Florida teachers for licensure. There is a section that assesses your knowledge of the processes of life, some of which are reviewed in this chapter, and it accounts for approximately 14% of your final score. The FTCE Middle Grades General Sciences consists of about 120 multiple-choice questions and test takers will have two and a half hours to complete the exam.
1. 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.
2. 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.
3. 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.
4. 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.
5. The Electron Transport Chain: Products and Steps
In this lesson, we'll learn about the finale of cellular respiration. The electron transport chain uses products from the first two acts of glycolysis and the citric acid cycle to complete the chemical reaction that turns our food into usable cellular energy.
6. Lactic Acid & Alcoholic Fermentation: Comparison, Contrast & Examples
When in an anaerobic environment, some cells can use glycolysis and fermentation to keep producing ATP. Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.
7. Chlorophyll: Absorbing Light Energy for Photosynthesis
Plants are clean, green, photosynthesizing machines. Using a specialized pigment called chlorophyll, plants are able to soak up energy from the sun and turn it into food. In this lesson, we'll start to learn why chlorophyll literally gets excited about a sunny day!
8. Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products
In this lesson, we'll learn how electrons get excited during the light-dependent reactions of photosynthesis, jumping off photosystem reaction centers like they were trampolines! In addition, we'll learn how the splitting of water creates reactants for this part of photosynthesis while creating a little fresh air for us.
9. Dark Reactions of Photosynthesis: The Calvin-Benson Cycle
Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.
10. Plant Respiration: Definition & Process
Cellular respiration is essential to the survival of all plants and animals. In this lesson, we'll look at what plant respiration is, why it is important, and the three main phases involved in the process.
