Organic Chemical Reactions: Redox, Esterification & Fermentation

1. Organic Chemical Reactions: Redox, Esterification & Fermentation

There are many different types of reactions that occur in organic chemistry. This lesson will highlight three reactions, explaining which organic molecules are the reactants and which are the products, as well as what occurs during the reaction.

Cellular Respiration: Energy Transfer in Cells

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.

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

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.

Gluconeogenesis: Definition, Steps & Pathway

4. Gluconeogenesis: Definition, Steps & Pathway

In this lesson, we will learn about gluconeogenesis, what it is, and why it is important to the body. We will also learn what can be used as a precursor to gluconeogenesis.

Glycogenolysis: Definition & Pathway

5. Glycogenolysis: Definition & Pathway

In this lesson we will learn about glycogenolysis and how it provides glucose for energy in the body. We will learn how the glucose is stored and how glycogenolysis get the glucose out of storage form and into the body.

Glycolysis Pathway: Steps, Products & Importance

6. 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 Pentose Phosphate Pathway

7. The Pentose Phosphate Pathway

There are hundreds of various chemical reactions that occur within cells. In this lesson, we are going to check out one of those reactions, called the pentose phosphate pathway. Let's see what this reaction is, as well as what it produces and why it's important.

The Citric Acid (Krebs) Cycle: Products and Steps

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.

The Electron Transport Chain: Products and Steps

9. 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

10. 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.
