So basically, let's suppose we have a single particular type of enzyme that we're studying and this is our enzyme. It could be any type of enzyme found inside our body. So the enzyme, it's active side. So these are the substrate molecules and these are the product molecules. What the turnover value tells us what the turnover number tells us is the total number of substrate molecules that can be transformed into the product molecules per unit time, for example, per second, when only a single active site, a single enzyme is actually being used. Now, to demonstrate how this actually works and how we can calculate the K two value, let's take a look at the following hypothetical example.
