Enzyme Action

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.

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!

More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function.  Topics like the chemistry behind efficiency of enzymes, factors that affect speed of reaction,...

Enzymes really know how to keep things moving along! Introduce these powerful proteins through a short video from an extensive life science playlist. Viewers learn why enzymes are specific in their jobs, important enzymes in our bodies,...

He is the substrate to her enzyme! The video describes why enzymes are important. It details their functions, how they relate to substrates, and why they are found in so many places. The resource is part of the Fuse School playlist.

Many people know enzymes help with digestion, but few realize enzyme production decreases with age, making it more difficult for bodies to digest certain foods. A instructional activity offers 28 fill-in-the-blank and short-answer...

Enzymes: not just for breaking chemicals apart. Young biologists perform an experiment on potatoes. They first remove starch from potato extract. They then add the resulting liquid to samples of glucose-1-phosphate, glucose, maltose, and...

Milk the resource for all it's worth. Young biologists perform assay techniques to test the digestion of protein. They place bacterial samples, fungal samples, trypsin solution, and distilled water on a milk-agar plate to see the effects...

Sugar isn't good for you, but it's great for microbes. A simple experiment has pupils investigate the digestion of starch by microbes to produce sugars. They apply two bacterial cultures, an amylase solution, and distilled water on a...

Learners test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...
