This is a good page for explaining the development and function of enzymes. It includes links to help with the chemistry and the biology that comes up.

Investigate how enzymes facilitate chemical reactions that happen in the body with this tutorial.

Reactions in cells must be regulated and one way to do this is using allosteric molecules. These regulators can activate enzymes or inhibit them. This tutorial explains exactly how allosteric regulation works using words, narration, and...

The discovery of restriction enzymes and their applications in DNA analysis has proven to be essential for biologists and chemists. This lesson focuses on restriction enzymes and their applications to DNA analysis and DNA fingerprinting....

[Free Registration/Login may be required to access all resource tools.] In this lesson, students will define enzyme, be able to discuss the role of enzymes in biochemical reactions, and summarize their importance to living organisms.

How well do you know the relationship between enzymes and activation energy? This resource provides you with short quizzes and tutorials to provide feedback for those topics you don't understand.

[Free Registration/Login may be required to access all resource tools.] This activity describes how enzymes speed up biochemical reactions and their importance to living organisms.

[Free Registration/Login may be required to access all resource tools.] Chemical digestion could not take place without the help of digestive enzymes. An enzyme is a protein that speeds up chemical reactions in the body. Digestive...

Animated learning exercise about all types of enzymes and their uses. Learn how different types of enzymes work and what effects them.

[Free Registration/Login may be required to access all resource tools.] Discusses the role of enzymes in biochemical reactions.

[Free Registration/Login may be required to access all resource tools.] Explores how enzymes work and their role in chemical reactions in living cells.

Through a combination of slide show tutorials and a video demonstration, learn how enzymes work. [3:00]

For this biology lab, students use pineapple juice as an enzyme, and jello as a substrate to illustrate an enzyme/substrate complex.

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.

Review over the factors that can control enzymatic activity with this article.

This lesson will describe how an enzyme is used to turn substrate into product. It is 4 of 5 in the series titled "Enzyme Function."

This lesson will describe that enzymes are made of proteins, and can be found in nature or can be synthesized synthetically. It is 4 of 4 in the series titled "Enzyme Structure."

This lesson will describe that enzymes are made of proteins, and can be found in nature or can be synthesized synthetically. It is 2 of 4 in the series titled "Enzyme Structure."

Learn about restriction digestion, where the result has sticky ends and blunt ends. Also find out about ligation reactions.

Slideshow notes introduce enzymes: their purpose, process, and importance.

Several animations illustrating how enzymes catalyze chemical reactions. Examine how temperature affects the enzymes and how toxins can alter the shape of the enzymes.

Searchable database of restriction enzyme information. Must have more than basic knowledge of restriction enzymes.
