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.

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...

The feedback mechanisms of metabolism of a variety of substances in the human body. Carbohydrates, lipids, amino acids, and their derivatives are explained. The biochemistry required to explain the metabolic balance and feedback controls...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Students explore how enzymes are important in the chemical reactions of all living things.  In this enzymes and catalysts lesson students complete an activity to see how enzymes change living things.

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

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.

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...

An informative lesson has learners read about, discuss, and study the classification, structure and importance of the following biomolecules: carbohydrates, proteins, lipids, nucleic acids, and enzymes. 

Use this great overview to give information on all aspects of nutrition. By working their way through this PowerPoint, students review a lot of information about the digestive process.  Students read many facts on a number of...

Pupils work with models of substrates and of enzymes and test the digestion of lactose with lactase. They determine if digestion of lactose has or has not occurred.

Students discover enzyme to substrate specificity. The experiment uses samples of glucose and lactose in combination with the enzyme lactase. Students observe the reaction between the lactose and the lactase; the lack of a reaction...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...

In this enzymes worksheet, students conduct an experiment to show how enzymes can be used to convert glucose to fructose. This worksheet has 1 short answer question.

AP biologists aspire to respire with this worksheet. In it, they write short answers to 26 questions about cellular respiration. Topics addressed include the Kreb's cycle, fermentation, and more. Written as a chapter reading...

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

In this anatomy worksheet, students complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of digestion.

Students experiment with lactase to find out how milk sugar is broken down in the body. In this enzyme lesson, students use glucose strips to investigate the breakdown of lactose into glucose and galactose for milk digestion in the human...

Storing and transferring energy is explained here with reference to the fight or flight response, along with the need for activity in times of lowered nutrition. This is a great summary of ATP applications, and after the multiple stages...

In this chemistry of food worksheet, students complete 20 various types of questions related to food and nutrition. First, they complete a crossword puzzle with vocabulary terms. Then, students use the figure shown to write the...

Students conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...

A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...

In this photosynthesis, disease and Immune System worksheet, students fill in the blanks with key terms to complete sentences about the transfer of energy from the sun to plants, enzymes as catalysts in reactions, homeostasis, the immune...

Young scholars experiment with enzymes as key components of chemical reactions in all living things through this series of lessons.
