Enzymes

Standard questions about enzyme activity are asked in this resource. Burgeoning biologists explain activation energy, enzyme specificity, inhibition, coenzymes, and more. This is a very neat worksheet, uncluttered and formatted to allow...

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

There will be no couch potatoes in your class when biologists experiment with potato enzyme activity. In this lab exercise, they will measure production by the amount of foam created. This resource has everything students need to carry...

After an explanatory introduction to sugars and enzyme activity, biochemists discover whether lactase is needed to digest lactose, sucrose, and milk as a whole. High school science lab skills are required for these investigations.

Teach your biology class about enzymes with this well-organized and impressive presentation. "Learning Check" and "Solution" slides are inserted throughout so that you can stop and have learners review. Why reinvent the wheel? Save...

Here is a five-star slide show that elaborates the topic of enzyme activity. With graphics that purposefully enhance the material, viewers learn about enzyme structure, function, and different roles that they play in a system. If you are...

The metaphors used here to describe the "cut and paste" procedures for genetic engineering will really help your biologists in their understanding of restriction enzymes and DNA.  The uses of genes that are isolated and incorporated into...

Dairy got you down? Your budding scientists learn what happens when lactase is broken down and what happens when it is not. The straightforward lab is easy to modify to a design-your-own or inquiry-based activity.

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...
