Pearson, as an active contributor to the biology learning community, is pleased to provide free access to the Classic edition of The Biology Place to all educators and their students. The purpose of the activities is to help you review material you have already studied in class or have read in your text. Some of the material will extend your knowledge beyond your classwork or textbook reading. At the end of each activity, you can assess your progress through _____ bind to the active site of an enzyme Self-Quiz. To begin, click on an activity title.

Concept 1: How Do Restriction Enzymes Work? Concept 11: Allelic Frequency vs. Concept 3: How Do Guard Cells Function? Concept 5: The Genetic Code: RNA vs. Enzymes catalyze reactions by lowering the activation energy necessary for a reaction to occur. In this laboratory, you will study some of the basic principles of molecular movement in solution and perform a series of activities to investigate these processes. Most chemical catalysts catalyse a wide range of reactions. They are not usually very selective. The proteins in enzymes are usually globular.

For two molecules to react they must collide with one another. An enzyme-catalysed reaction takes a different ‘route’. This is the simplest model to represent how an enzyme works. Each enzyme works within quite a small pH range. They block or distort the active site. Pectinase is used to produce and clarify fruit juices. Enzymes can be immobilized by fixing them to a solid surface. Of course catalytic proteins are in some ways no different from any others.

They are grouped here by the properties of their R-groups. RNA-protein complex of both 70S and 80S ribosomes. R-groups of each amino acid together. Enzymes carry all of this out by means of their conformation. The diagrams below show how the active site and a substrate combine.

PPO is shown here as a long ribbon. R-groups carried by the amino acids in the primary sequence. R-groups that were distant in the primary sequence! EDTA interacts with metal ions.
