Paul Andersen starts with a brief description of enzymes and substrates. He then explains how you can measure the rate of an enzyme mediated reaction. Catalase from yeast is used to break hydrogen peroxide down into water and oxygen. ...

“If you really want to know a people, start by looking inside their bedrooms," says Shereen El Feki, who traveled through the Middle East for five years, talking to people about sex. While those conversations reflected rigid norms and...

This video discusses the topic of minimum wages and aims to help the viewer understand their effects on labor markets and the associated advantages and disadvantages. The presenter explains what a minimum wage is and how it is typically...

Enzymes are really important proteins, that speed up the rates of reactions such as in photosynthesis, respiration and protein synthesis. The enzymes and substrates are always moving, and occasionally they collide at the right speed and...

Enzymes have optimal conditions under which they operate. Temperature, pH, enzyme concentration and substrate concentration are some conditions that affect the rate of reaction. As enzymes are proteins, they have an optimum temperature...

Secure Sockets Layer (SSL) has long been used to secure network communication on LANs and WANs. This episode discusses how Transport Layer Security (TLS) supersedes SSL in addition to continued backwards-compatibility support that...

This video is about the role of digestive enzymes in the chemical breakdown of large, insoluble molecules in our food into smaller, soluble ones. The video focuses on the three main types of digestive enzymes - carbohydrase, protease,...

This video is answering the question of why do wolves howl.

This video explains catalysts, exploring the concept of activation energy and how catalysts can lower it to speed up reactions. The video covers the use of catalysts in industry and domestic applications, including the catalytic...

Photosynthesis plays a huge role in regulating the earth's CO2. But what happens when the temperature gets high enough that photosynthesis slows down?

This video is the fourth of a four part course that covers the basic information that employees and managers need to know about gift and hospitality issues. It provides practical information, advice, tips, and a character connection.

In this video we examine the process of digesting our food. We shall see how biological catalysts called enzymes break these food molecules apart and why they are necessary. Think of our food molecules as a train of trucks all coupled...

Paul Andersen explains how organisms are able to regulate their internal body temperature (or not). He starts with a brief description conduction, convection, radiation and metabolism. He contrasts ectotherms and endotherms. He also...

For some reason, says educator Al Vernacchio, the metaphors for talking about sex in the US all come from baseball -- scoring, getting to first base, etc. The problem is, this frames sex as a competition, with a winner and a loser....

Microbes that live in extreme environments, like geysers and hydrothermal vents, are able to survive in extreme temperatures. Scientists have figured out ways to use this thermostability to supercharge DNA studies, including the study of...

hotosynthesis is a chemical reaction that is fundamental to life. In this video we are going to have a look at the factors that affect the rate of photosynthesis. There are 3 main factors: light intensity, carbon dioxide concentration...

So what is homeostasis is a term first defined by Claude Bernard in 1865 it means maintaining a constant internal environment this is a bit like car brain works senses all around the body imaging various things and sending the...

Molecules make you think of chemistry, right? Well, they also are very important in biology too. In this video we are going to look at carbohydrates, proteins and lipids. When I say lipids, I am talking about fats and oils. Life...

This video provides an explanation of homeostasis. The video discusses the importance of homeostasis, particularly in relation to enzyme action and cell function, and provides examples of homeostasis in the human body, such as the...

It's the most populous country in the world, and possibly the most powerful. But do you know as much about it as you think? Here's 10 Misconceptions Everyone Believes About China.

This video provides an explanation of what a catalyst is and how it can increase the rate of chemical reactions. The concept of activation energy is introduced, and it is explained that catalysts lower activation energy, allowing more...
