Enzymes

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!

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

Introducing enzymes and the controlling factors of a reaction this slideshow displays the typical rate of reaction graph and labels the main sections. The summaries of ways to measure reaction rates are valuable and the examples of...

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,...

It takes about seven seconds for food to move from the mouth to the stomach. Pupils follow food from the mouth through digestion, exploring where mechanical and chemical digestion occur. Saliva, enzymes, acids, and chyme are a small...

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...

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...

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...
