This site tells what lysosomes are and what their functions are. Also, the site discusses how the Golgi complex sorts lysosomal enzymes.

This passage will test your knowledge on enzymes.

This activity will use glucose strips to explore the function of lactase enzyme in milk. Students will try to understand the lactase enzyme to figure out the basics of lactose intolerance.

This lab activity provides students with the experience of using their own enzymes to convert starch to sugar (a disaccharide called maltose), then testing to see if the conversion has taken place.

In this biology simulation, students discover what factors influence the action of enzymes on cellular work. Students will first explore the action of enzymes through a simulation in which their hands are the enzyme "toothpickase" and...

In this activity, students understand the relationship between enzyme reaction rates and various environmental factors such as pH and temperature. They recognize the metabolic differences between endotherms and exotherms. They generate...

Students explore the shifting role of senescent cells throughout the lifespan of organisms. The article discusses cancer, Judy Campisi, and enzymes. The resource consists of pictures, quotes, and links to additional resources.

Explore practical uses of genetic engineering techniques to generate a plant that produces a hepatitis B protein for potential vaccine use. Examine the use of restriction enzymes for cloning and plasmid mapping.

NADH and NADPH are enzymes involved in cellular processes. Explains how NADH participates in catabolic reactions where energy is released and NADPH is involved in anabolic reactions where energy is consumed. Their functions and chemical...

Students learn about molecules, cells, and systems. Some topics investigated in the tutorial are cell types, enzymes, plasma membranes, and the heart.

[Free Registration/Login may be required to access all resource tools.] How catalysts work and their role in living things.

Animated slide show demonstrates the genetic engineering process of DNA restriction.

Take a look inside the human body's digestive system. This site features diagrams of the digestive tract and each part is accompanied by labels and descriptions. Just select an organ by moving the mouse over its image.

Practice for the MCAT by answering questions on Glucose-6-Phosphate Dehydrogenase Deficiency.

Wath an animation that shows how enzymes break down glycogen into glucose subunits.
