About This Chapter
CSET Cell Biology & Physiology: Respiration and Reactions - Chapter Summary
By watching our video lessons, you will learn how to explain energy transfer in cells during cellular respiration. During this chapter, you will study in the following concepts:
- The electron transport chain
- Alcoholic fermentation and lactic acid
- Enzyme functions
- The citric acid cycle
- The glycolysis pathway
- The mitochondria structure
Additional topics covered in our CSET Cell Biology & Physiology: Respiration and Reactions chapter include enzymatic and redox reactions, electron carriers, anabolic pathways and catabolic pathways. We offer you content through short, easy-to-digest video lessons, as well as supplementary quizzes that test your knowledge over respiration and reactions. Our quizzes help you reveal your strengths and weaknesses through immediate feedback. You can use your results to determine your preparedness for respiration and reactions questions on the CSET Science test.
CSET Cell Biology & Physiology: Respiration and Reactions Objectives
As indicated by the CSET Science test objectives, you will need to describe how mitochondria are important in the cellular respiration process. The CSET Science test has two general science subtests and one specialization subtest. For the specialization subtest, you will need to select from Earth/planetary science, chemistry, biology/life science or physics concentrations.
These video lessons prepare you to answer questions on the biology/life science subtest. While the specialization subtest contains 50 multiple-choice and three constructed-response questions, each general science subtest has you answer two constructed-response and 58 multiple-choice questions.
1. Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane
If you want to make it through the day, you're going to need some energy. In this lesson, we'll learn about the organelle that supplies this energy, the mitochondrion, and why this cell structure appreciates the time you took to eat breakfast this morning!
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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!
10. 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.
