You have a bunch of pieces in a plastic container, and you take out the shapes you need.

You can put them together to build structures, or take them apart and hopefully put them back in the bucket so your parents don't trip on them.

We'll also go over some examples of allosteric regulation in the body.

Have you ever played with Legos or building blocks as a kid?

There are two forms of hemoglobin, the T state (or tense state), which makes hemoglobin bind oxygen less tightly, and the R state (or relaxed state), which makes hemoglobin bind oxygen more tightly.

Now, this might give you the impression that the T state is bad since it prevents hemoglobin from binding oxygen.Try it risk-free In this lesson, we'll review what enzymes are and how they work.Then, we'll learn what the allosteric site is on an enzyme and how it influences enzyme activity.Although this is a simple analogy, small molecules inside the cells of your body, called enzymes, serve a similar function by making and breaking apart other molecules. A catalyst is something that increases the speed of a reaction.Enzymes speed up chemical reactions that are used to build structures in your cells or break them down.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.How hot or cold the environment is, the p H, the location in the body, and what other substances are around all influence enzyme activity.Some substances bind the enzyme at a site other than the active site. The allosteric site allows molecules to either activate or inhibit, or turn off, enzyme activity.The substrate is the name for the substance an enzyme works on.The substrate binds to the active site, or the place on the enzyme that actually does the work.
