Hydrogen peroxide bubbles might look painful on a cut, but they are actually doing an important job. The video explores enzymes by allowing learners to see active sites on enzymes and how substrates, like a key fitting a lock, fit within the active site. The video also shows the roles of cofactors and coenzymes.

Instructional Ideas

• Look online for the enzyme lab referenced in the video and incorporate it into class
• Have other examples of enzymes and walk learners through their effects on reactions

Classroom Considerations

• Must have a computer, Internet access, and projection system
• Part 20 in a series of 37

Pros

• Includes two enzymes review worksheets
• References an enzyme lab used in class to explain reaction rates
• Great, simple visuals showing substrates and active sites

Cons

• None
