In this video, we're going to begin our lesson on enzyme binding factors by introducing the enzyme-substrate complex. When an enzyme interacts with its substrate, the substrate binds to the enzyme specifically at a region called the active site. When the substrate binds to the enzyme at the active site, this ends up forming the enzyme-substrate complex. The enzyme-substrate complex is commonly abbreviated as just ES. So, I'll put ES here. The active site, once again, is defined as a very specific region of an enzyme that binds the substrates. Let's take a look at our image down below to look at how substrate binding forms the enzyme-substrate complex. Notice over here on the far left, we're showing the enzyme in red, and the enzyme is commonly abbreviated with just an e. Notice that in black right here, we're showing you the substrate which is really acting as the reactant for this enzyme-catalyzed reaction, and substrates are commonly abbreviated with just the letter s. Notice that the substrate here is going to bind to the active site of the enzyme, which is just this region that we see right here. This other region over here is not the active site. The active site is just a specific region on the enzyme that binds the substrate. Once the enzyme is bound to the substrate, it ends up forming the enzyme-substrate complex. Here in the middle, we can see the substrate is bound to the enzyme, and they are making this fit together. The enzyme-substrate complex is commonly abbreviated as just ES complex. Now after enzyme catalysis, the products are going to be released from the active site, and the enzyme will remain unchanged in the reaction. Notice that after enzyme catalysis, represented by this arrow right here, the substrate in black is being converted into the product over here, which is in green, and the products are commonly abbreviated with just a p. Notice that the enzyme is actually unaltered; it remains unchanged by the end of the reaction. The enzyme still takes on the original form that it had before the reaction took place. This is what we mean by the enzyme being unchanged. Because the enzyme is unchanged, it means it can continuously catalyze this reaction over and over again to continuously make more and more products over time. This concludes our introduction to the enzyme-substrate complex. As we move forward, we'll be able to talk about some more enzyme binding factors. So, I'll see you all in our next video.
