1. Biochemical Reactions: Synthesis and Decomposition
Did you know that there are thousands of chemical reactions going on in your body every day? In this lesson, you will learn about three types of biochemical reactions: synthesis reactions, decomposition reactions and reversible reactions.
2. 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!
3. Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions
Some enzymes require helpers to recognize a substrate or complete a reaction. These helpers include cofactors, coenzymes, and prosthetic groups, which are required for some enzymes' functions.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. Human Growth Hormones: Uses & Side Effects
This lesson is about human growth hormone, or HGH. We will discuss what HGH is, its normal function in humans, conditions for which it is prescribed, its side effects, and ways it has been abused for unintended use.
12. Keratin Protein & the Epidermis
This lesson is about keratin and its role in the epidermis, or the skin. We will talk about what the skin is made of, what keratin protein looks like, how it works inside the skin, and what happens when keratin creates disease in the skin.
13. The Three Processes of Urine Formation
Urine may be a waste product, but it is a carefully created waste product. There are three main stages in urine formation, and this lesson covers them all!
14. Calcium Ions: Definition & Formula
Have you ever heard of a calcium ion? Did you know that is it super important to your everyday life? Luckily you have come to the right spot! In this lesson, you'll learn what a calcium ion is, why it is important and how to identify it.
15. Alcohol Myopia: Theory & Definition
This lesson will describe the theory of alcohol myopia and how it relates to alcohol ingestion. Additionally, it will define the condition along with a short description of how alcohol affects the body.
16. Synthesis Reaction: Definition, Formula & Examples
Synthesis reactions, the act of combining two or more substances together to make a product, occur all around us, from the kitchen to our chemical laboratories. In this lesson, learn more about this amazing reaction, its formula, and examples.
17. Tetramer: Definition, Analysis & Immunology
Have you ever wondered how doctors can detect viruses or even cancer by doing a blood test? Maybe, you've wondered how doctors can detect cancer before a person even has symptoms. This lesson will explain how tetramers are one of the many modern techniques used to detect the presence of a disease.

26. What Are Complete Proteins? - Definition & Food Examples
Proteins are the body's building blocks and without them life would not be possible. But not all proteins are created equal. Some proteins are considered complete, while others are incomplete and need to be combined in order to be utilized properly. Understanding complete proteins can help an individual improve their diet and overall health.
