 So now we're pretending we're like the small lab group because eventually you're going to do the same thing But you're going to be the group doing this. All right, and what were some central ideas you saw out of that? that text from that like even though Exergonic reactions happen spontaneously they may take a really long time To happen so if you add an enzyme it'll like speed it up a lot. Good. All right, and where were you pulling that from? Is that the first paragraph? Yeah, the first paragraph. All right, so let's try and bring that alive All right, so this is the model system We're going to use to try and make sense of the text visually. All right So what Carson was saying there was right? This is our sucrose. All right, it's our glucose and our fructose right and Is it going to hydrolyze? Slowly right, but what if we look at this over here, right and we have the same thing We have the glucose and the fructose together it combines to make sucrose and the sucrose molecule collides with the enzyme All right, and notice what's going to happen. The enzyme is going to change its shape All right, and that is going to contort the sucrose All right, and so how are we going to represent it with this model is you see this oxygen right there? Now that oxygen That is a very important bond. Do you remember back from our carbohydrate days? car car But instead today right today work that in we got sucrose so starch and sucrose today, right? so this is a glycolink it's the bond that's holding this together and this enzyme is going to contort it during this collision and It's going to change the shape of it now That's how I'm representing it two-dimensionally with this model system. All right, and then what's going to be the result of that? It's going to do hydrolysis. What does that mean? What is hydrolysis mean? What are we going to do? What does hydro mean? Take those terms and apply them to the model system we have What you literally do is going to be the same, but we should be able to apply more terminology to that process What terminology can we add to this same? system we've been using here The sucrose is the substrate and That well when it's connected with the enzyme in the H2O is on the like the Carbo bond right there in the middle of the bond H2O is there. That's the enzyme substrate complex Okay, so when they're connected connected. Yeah, basically and The active site is like where everything connects where the sucrose connects so this yeah the purr the pink perfect Yeah, and the induced fit is When the little flaps I guess like fold to meet the shape of the sucrose
