Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

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.

Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils...

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Now you have a new excuse not to do your homework. A long-term experiment has learners explore cellulose-digesting enzymes. They simulate how paper breaks down in a compost bin. There's no need to blame your dog for eating your homework...

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...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

A 17-page practice final exam for a college-level introductory biology course is contained in this resource. Matching and short answer questions cover every topic that you would expect to teach during an advanced biology course including...

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

Middle schoolers 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...

Although biochemistry of the human body is a vital topic, it doesn't have a chapter dedicated to it in many biology textbooks. If that's the case with your text, you can use this resource as a guide for designing your own lecture and as...

Biology aces analyze restriction maps to determine the relationships among different primate species and then complete a cladogram. Preface this lesson with an explanation of how restriction enzymes are used to create the DNA maps....

In this living environment worksheet, students answer a variety of questions about living organisms, the processes they go through to make food and break down food, absorb nutrients, and release toxins. They explain homeostasis, they...

Students pretend to be enzyme that breaks toothpicks in timed intervals. They complete calculations to determine how many toothpicks are broken per second to determine the rate of reaction of the enzyme.

Students are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...

Students can use an O2 Gas Sensor to measure the amount of O2 produced when H2O2 is broken down by the enzyme catalase at different concentrations, pH values, and temperatures. They will also measure the enzyme's initial reaction rates.

By using inquiry skills, students will design and complete a lab investigation to gain an understanding of the concept of enzymes.

The purpose of this set of problems is for you to become familiar with some key principles about enzymes, catalysis and energy. The correct answers for the multiple choices problems are reinforced with a brief explanation and the...
