The Cell: Structure & Function

1. The Cell: Structure & Function

The cell is a small, but complex structure. Take a look inside the outer plasma membrane of a cell and discover the functions of some common cellular components, including the nucleus, endoplasmic reticulum, Golgi apparatus and mitochondria, in this lesson.

Anabolism and Catabolism: Definitions & Examples

2. 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.

Oxidation & Reduction Reactions in the Metabolism: Process & Significance

3. Oxidation & Reduction Reactions in the Metabolism: Process & Significance

Oxidation and reduction reactions, collectively known as redox reactions, take place in body cells and are important for the production of energy, namely ATP. Oxidation involves the loss of electrons and reduction involves the gain of electrons.

Cellular Respiration: Energy Transfer in Cells

4. 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.

Glycolysis Pathway: Steps, Products & Importance

5. 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.

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.

The Citric Acid (Krebs) Cycle: Products and Steps

7. 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

8. 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.

Beta Oxidation: Definition & Steps

9. Beta Oxidation: Definition & Steps

In this lesson, you'll discover what beta oxidation is and what it is used for. You'll also learn a little bit about fatty acids and the steps involved in their breakdown.

Effects of Feasting & Fasting on Cells

10. Effects of Feasting & Fasting on Cells

Your cells use the nutrients from the foods you eat to fuel vital functions. If you eat too much (feast), excessive nutrients get pushed into storage. If you eat too little or not at all (fast), stored nutrients can be pulled out of storage and used to meet your body's needs.

Glycogenesis, Glycogenolysis, and Gluconeogenesis

11. Glycogenesis, Glycogenolysis, and Gluconeogenesis

Your body uses processes to keep blood glucose levels within the normal range. Learn how your body decreases blood glucose levels through glycogenesis and how it boosts glucose levels through glycogenolysis and gluconeogenesis in this lesson.

Protein Synthesis in Cells: Process & Importance

12. Protein Synthesis in Cells: Process & Importance

The DNA of the cell contains the blueprints for all the proteins in the body. These blueprints become proteins with the help of RNA and ribosomes. Follow along with this lesson to learn about the two major phases of protein synthesis: transcription and translation.

Lipogenesis: Process & Function

13. Lipogenesis: Process & Function

Lipogenesis is the process your body uses to convert carbohydrates into fatty acids, which are the building blocks of fats. Fat is an efficient way for your body to store energy. Learn about the importance of acetyl-CoA and insulin in lipogenesis.

Alcohol Metabolism: Process & Effects

14. Alcohol Metabolism: Process & Effects

Alcohol is broken down in the liver with the help of enzymes. Learn how alcohol is converted to the toxic byproduct acetaldehyde before being oxidized into acetate with help from the enzymes alcohol dehydrogenase and aldehyde dehydrogenase in this lesson.
