20 Lessons in Chapter 9: Cell Metabolism: Help and Review
Cellular Respiration: Energy Transfer in Cells

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.

Redox Reactions & Electron Carriers in Cellular Respiration: Definitions and Examples

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.

Glycolysis Pathway: Steps, Products & Importance

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.

The Citric Acid (Krebs) Cycle: Products and Steps

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.

The Electron Transport Chain: Products and Steps

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.

Lactic Acid & Alcoholic Fermentation: Comparison, Contrast & Examples

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.

Chlorophyll: Absorbing Light Energy for Photosynthesis

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!

Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products

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.

Dark Reactions of Photosynthesis: The Calvin-Benson Cycle

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.

Cell Growth: Phases & Factors

10. Cell Growth: Phases & Factors

This lesson provides an overview of cell growth and division. It includes descriptions of how major cell types divide, why cell growth and division are important, and images to guide your understanding. The lesson is followed by a short quiz.

Starch vs. Cellulose: Structure & Function

11. Starch vs. Cellulose: Structure & Function

In this lesson, you will discover what starch and cellulose are. You will also learn the difference between them and how that difference affects their individual functions.

Starch vs. Glycogen: Structure & Function

12. Starch vs. Glycogen: Structure & Function

In this lesson, we'll discuss starch and glycogen, their relationship to glucose, and how they are used by both plants and animals differently to survive. Then, take the quiz to test what you learned.

Starch: Structure, Types & Examples

13. Starch: Structure, Types & Examples

In this lesson, we'll go over what the structure of starch is and what it's made of, as well as examples of different types of starch. Then, you can test your knowledge with a brief quiz at the end.

Thyroglobulin & Anti-Thyroglobulin Antibodies

14. Thyroglobulin & Anti-Thyroglobulin Antibodies

This lesson will allow you to discover what thyroglobulin is, what it does, as well as describe its important role in the body. In addition you will learn what anti-thyroglobulin antibodies are and their clinical usage.

Thyroxine: Definition & Function

15. Thyroxine: Definition & Function

In this lesson, we'll look into the function of the thyroid gland, how the hormone thyroxine works to stimulate your body's metabolism, and what can happen if the thyroid gland and its hormones don't function properly.

What Is ADP in Biology?

16. What Is ADP in Biology?

In living things, there are certain molecules that act like batteries, giving us the power to perform everyday functions and stay alive. In this lesson, learn about ADP, an important part of the 'rechargeable' battery in your body and how it works.

What is an Ester Linkage?

17. What is an Ester Linkage?

This lesson will cover the structure of an ester, how they are formed, and types of ester linkages found in nature. You'll learn about esters composed of two hydrocarbon linked by an oxygen atom, phosphoesters, and nitroesters.

What is Metabolic Waste? - Definition & Products

18. What is Metabolic Waste? - Definition & Products

The word metabolism is often used in conjunction with someone's shape and size, but metabolism is actually a complex set of reactions that take place in our cells. We'll talk about how it works and what metabolic waste is left over afterwards.

What is Starch? - Definition, Function & Chemical Formula

19. What is Starch? - Definition, Function & Chemical Formula

In this lesson, you'll learn what starch is composed of and some foods that contain it. In addition you will discover more about the chemical components of starch as well as its function inside and outside the body.

Organelles Involved in Protein Synthesis

20. Organelles Involved in Protein Synthesis

This lesson provides an overview of the process of protein synthesis and the organelles it involves. It follows the path of an mRNA molecule from the nucleus to the ribosomes, where proteins are synthesized.
