TExMaT Master Science Teacher 8-12: Biochemistry of Life - Chapter Summary
Increase your knowledge of redox reactions, fermentation processes and other elements of biochemistry when you watch these video lessons. Prepare for the TExMaT Master Science Teacher 8-12 examination while reviewing the steps and definitions related to aerobic cellular respiration, photosynthesis and light reactions. This chapter aims to help you to:
- Understand the role of electron carriers in cellular respiration
- Explain the transfer of energy in cells
- Discuss the significance of glycolysis pathway
- Describe the citric acid cycle and the electron transport chain
- Compare alcoholic fermentation and lactic acid fermentation
- Understand the functions of chlorophyll and the steps involved in photolysis
- Describe the Calvin-Benson cycle
Teachers who have extensive knowledge of biochemistry present the material in these videos. You have the option of studying whenever you like and wherever you have access to the Internet as you prepare to take the TExMaT Master Science Teacher 8-12 examination. Optimize the learning experience by asking questions, consulting the text transcripts and taking the lesson quizzes.
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.
