Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

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

Explore enzymes in 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...

[Free Registration/Login may be required to access all resource tools.] Definition of a biochemical reaction, the different types and the importance of enzymes in biochemical reactions.

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."

This lesson focuses on enzyme-catalysed reactions and the effect of temperature, substrate concentration, and pH on the reaction rate. It provides a link to an assessment.

This virtual laboratory demonstrates how an enzyme-linked immunosorbent assay (ELISA) is carried out and some of the key experimental problems that may be encountered. Students will learn about the assay procedure and the equipment and...

[Free Registration/Login may be required to access all resource tools.] In this module, students investigate amino acids, peptide bonds, and proteins. They also have the opportnity to discover the effect of an enzyme on a biochemical...

Through interactive learning exercises, students examine the different definitions of energy and how enzymes regulate how the energy is stored and used during cellular respiration. They also take a close look at photosynthesis to learn...

Most structural components of the cell are made up, at least in part, by proteins and virtually all the functions that a cell carries out are completed with the help of proteins. This site explains protein synthesis, including that of...

This lesson will describe the process of induced fit, and explain how enzymes use it during chemical reactions. It is 2 of 3 in the series titled "Induced Fit."
