Understand how enzymes work with this page that includes animations and explanations. Learn that all enzymes are proteins and have specific catalytic actions.

View this simulation to observe the docking process for a substrate and an enzyme.

Explains sources of rennin and what its functions and uses are.

Learn about the critical role enzymes play in supporting life as you play games and solve puzzles, and do virtual experiments. Then take a quiz to check your understanding.

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.

Do this activity to find out how to make milk curdle.

A short, informational article which explains the structure and function of peroxisomes inside a cell.

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...

Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. If you like chemical reactions that stink and ooze foamy bubbles...

Pizza, milk shakes, and ice cream sundaes all contain dairy products, therefore they cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet...

What is a catalyst? This Khan Academy resource includes examples of enzymes, acid-base catalysis, and heterogeneous (or surface) catalysis.

Learn the roles of DNA polymerases and other replication enzymes. Understand the leading and lagging strands and Okazaki fragments.

[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...

Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change...

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...

Here you can learn about biochemistry, the chemistry of the living world. Content explores carbohydrates, lipids, amino acid structure and proteins, enzymes, nucleic acids, and metabolism.

This is the index page for a slide series on cell energetics. Among the topics covered in the series is the role of enzymes in the metabolic process. Use the topic list to go straight to any slide.

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."
