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

Chemical reactions are constantly happening in your body - even at this very moment. But what catalyzes these important reactions? Vance Kite explains how enzymes assist the process, while providing a light-hearted way to remember how...

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....

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.

This tutorial takes a brief look at enzyme activity and how enzymes work as catalysts.

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.

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

This lesson shows that an active site is the space on an enzyme where a substrate would attach. It is 4 of 4 in the series titled "Active Site."

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

Learn about activation energy, transition state, and reaction rate.

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

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint")...

This lesson presents how the structure and function of enzymes pertain to living things. It is 3 of 4 in the series titled "Structure and Function of Macromolecules: Enzymes."

This lesson presents how the structure and fun#tion /f enzymes pertain to living things. It is 4 of 4 in the series titled "Structure and Function of Macromolecules: Enzymes."

This lesson shows that an active site is the space on an enzyme where a substrate would attach. It is 3 of 4 in the series titled "Active Site."

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...
