Endotoxins: Definition & Examples

1. Endotoxins: Definition & Examples

Let's investigate the potentially deadly endotoxins. Endotoxins are a substance unique to gram-negative bacteria. Uncover how our immune system copes with endotoxins and their associated health effects in this lesson.

Enzyme Rate of Reaction: Factors & Catalysts

2. Enzyme Rate of Reaction: Factors & Catalysts

What is an enzyme? Why are they important? How can they change? This lesson answers those questions. It teaches us how enzymes work and how they can be changed. It also includes illustrations, examples, and a brief quiz.

Pyruvate Oxidation: Products & Overview

3. Pyruvate Oxidation: Products & Overview

During one phase of aerobic respiration, pyruvate is oxidized in order to release energy. This lesson will discuss the various processes required to break down pyruvate and the resulting products that are formed.

What Are Digestive Enzymes? - Functions & Types

4. What Are Digestive Enzymes? - Functions & Types

We are what we eat. But that doesn't mean our blood vessels are filled with giant chunks of hamburger. Thankfully, digestive enzymes help break down food into sizes small enough to be absorbed into our bloodstream. In this lesson, learn about these vitally important proteins.

Enzyme Regulation: Mechanisms & Types

5. Enzyme Regulation: Mechanisms & Types

This lesson reviews what an enzyme is and its functions. It further discusses mechanisms that regulate enzymes as well as different types of enzyme regulation and concludes with a short quiz.

Histidine: Structure & Function

6. Histidine: Structure & Function

You know that when you eat meat you are eating protein; however, did you know proteins are made up of building blocks called amino acids? In this lesson, you will learn about the structure and function of the amino acid histidine and then be able to check your understanding with a short quiz.

What is Biosynthesis? - Definition & Overview

7. What is Biosynthesis? - Definition & Overview

Biosynthesis is a process in the body that builds complex structures out of simple ones. Check out this lesson to learn more about biosynthesis, including different types and examples, and then test your knowledge with our quiz!

Activation Energy of Enzymes: Definition, Calculation & Example

8. Activation Energy of Enzymes: Definition, Calculation & Example

With this lesson you will understand what the activation energy of a chemical reaction is. You will also learn what enzymes are and how they affect chemical reactions.

Amine: Definition, Structure, Reactions & Formula

9. Amine: Definition, Structure, Reactions & Formula

What does the fried fish you eat and dog poop have in common? The answer is amines. In this lesson, we will learn about the chemical structure of amines and how they react.

Carrier Proteins: Types & Functions

10. Carrier Proteins: Types & Functions

In this lesson, you'll learn the definition of a carrier protein. Also, you'll explore the types of carrier proteins and find out how they each assist molecules as they pass through the cell membrane.

Electrolyte: Definition & Examples

11. Electrolyte: Definition & Examples

Electrolytes are charged particles that are critical for biological systems. They play a role in many of the bodily functions of humans and must be maintained for proper health. This lesson discusses electrolytes and their role in the body.

Enantiomers: Definition, Properties & Examples

12. Enantiomers: Definition, Properties & Examples

Just like how our hands are mirror images of each other, molecules can also have mirror images that cannot be superimposed on each other. These molecules are called enantiomers. In this lesson, we'll discuss their properties and show some examples.

Inhibitors: Definition & Types

13. Inhibitors: Definition & Types

In this lesson, we introduce the concept of a chemical inhibitor, how chemists use them to stop or modify reactions, and common types of chemical inhibitors you may encounter in everyday life.

What is Sucrose? - Function, Structure & Chemical Equation

14. What is Sucrose? - Function, Structure & Chemical Equation

Sucrose is a type of sugar that is present in almost everything we eat. It is a natural compound and one that gives us valuable energy, but it can be harmful when over-consumed.

Enzyme-Substrate Complex: Definition & Overview

15. Enzyme-Substrate Complex: Definition & Overview

Enzymes are almost everywhere in your body. Discover where they are found, how they work and why they are important. Learn two models for how the enzyme-substrate complex is formed as well as the changes that could cause this bonding to fail.
