Amylase

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

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...

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,...

Colorful pictures and animation accompany a thorough explanation of the digestive process. Each anatomical part of the digestive system is explained as well as the chemical signals that are affiliated with digestion and absorption....

Students examine the basics of starch and how it is used in food. In this photosynthesis lesson plan students experiment with variables that affect starch production in photosynthesis.

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...

Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

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 worksheet offers 28 fill-in-the-blank and short-answer questions over...

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...
