You see that rim of the enzyme that is called that Active Site!! The Active Site is the only place that enzymes and substrates can become a whole because of how that area is specially shaped to fit around the substrate.
These are some examples of how the Active Site is a specially shaped area of the enzyme that fits around a substrate. This demonstrates the lock and key method that I was telling you about earlier.
When enzymes are finally finished with their job they let go of the substrate and they are ready for another reaction but the substrate is no longer the exact same. The substrate is now called a Product because of its change.
As Enzymes go from substrate to substrate enzymes may start to be controlled after they finish their job. They can be controlled by poisons but denaturing can occur. Denaturing occurs when the controlled enzyme shape is changed. There are four ways Enzymes can be controlled.
These four Enzyme controls do different things to the enzymes. Temperature changes the shape (denature), Activators make enzymes work faster someone either eats a candy bar or the body creates and activator, pH Levels will change the shape like temperature, and finally Inhibitors slow down or STOP the activity of an enzyme.
pH 0-14 pH
Well you learned all about me!! Trust me I will see you soon, and remember my name is Pepsin the Enzyme. Ok now I am gonna go break-down those substrates!!
