Enzyme structure and function

6 videos
1A: The multitude of reactions within our cells are sped up by enzymes. Without these biomolecules, these biochemical pathways would be as slow as a turtle. For instance, without enzymes, your body may never be able to break down and absorb the hamburger you just had for lunch. The hamburger would simply sit there, a lump in your stomach, until reactions slowly started to happen on their own - enzymes speed that up!

Introduction to enzymes and catalysis

VIDEO 6:05 minutes
Let's explore what enzymes are, and how they can affect a reaction. The most important affect you need to know is its ability to "catalyze" the reaction. By Ross Firestone.

Enzymes and activation energy

VIDEO 5:32 minutes
Explore the role of enzymes in making a reaction more likely to happen quickly. By Ross Firestone.

Induced fit model of enzyme catalysis

VIDEO 6:44 minutes
Get a better appreciation for how enzymes and substrates bind together. By Ross Firestone.

Six types of enzymes

VIDEO 7:04 minutes
Enzymes are often named for their reactions, and you can often discern the function of an enzyme from its name. We will learn about six types of enzymes based on the type of reaction they catalyze. By Ross Firestone.

Co-factors, co-enzymes, and vitamins

VIDEO 5:21 minutes
Co-factors and co-enzymes assist enzymes in their function. We will learn what both co-enzymes and co-factors are, and how they might affect the catalysis of a reaction. By Ross Firestone.

Enzymes and their local environment

VIDEO 4:31 minutes
In this video, we'll learn how different environments might affect an enzyme's function. Important environmental factors include pH and temperature. By Ross Firestone.
