Curated OER
An Enzyme- Substrate Model
Young scholars explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.
Curated OER
Restriction Enzymes
Learners explore enzymes and enzyme combinations. They examine and cut up and practice matching DNA sequences.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Enzyme Action
Students 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.

How do Restriction Enzymes Work?
Students discover how restriction enzymes work, while learning the importance of restriction enzymes in studying DNA structure.
Baylor College
Digestion
Digestion is an amazing and complicated process that provides humans with the energy they need to survive. Lesson six in this series on the science of food uses sliced turkey and a meat tenderizer to demonstrate how enzymes help break...

DNA Replication
Students are able to distinguish between transcription and replication. They are able to distinguish between DNA and RNA. Students name some of the proteins and enzymes used in replication and transcription. They are able comprehend the...
Curated OER
CELL TRANSFORMATION IN TOBACCO LEAF DISKS
Learners work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for...
Curated OER
Dinosaur and DNA Days
Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...
Curated OER
Enzyme Lab
Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.
