Now, the urea cycle is made up of 4 reactions, yes, but it has a lot involved with it. We have different types of metabolites and different types of enzymes involved. To help us memorize these, we're going to utilize 2 memory tools. The first memory tool is going to help us memorize the metabolite names. So here, we're going to say, when it comes to memorizing or remembering the urea cycle, the reaction of the urea cycle can be remembered by memorizing the metabolite names. So before we talk about this memory tool, just a little bit of history about me. So I am Jules Bruno Junior. My father's name is Jules Bruno. My father was a cab driver for nearly 30 years in Miami, Florida. At different times after school when he picked me up, I'd be in the cab with him. I'd hear interesting conversations with each of his fares. And this kind of inspires this memory tool. So if we take a look at this memory tool, we're going to say here that ordinary carpooling citizen and we're going to say here, aspires arranged success, and it's going to fuel arguments and utters opinions. So, ordinary carpooling citizen in a cab, we're going to say Aspires Arranged Success. So that can be any success of the people being ridden in the cab. That can mean a lot of things. Fuels arguments. I've heard some interesting debates between the people in the car, the people on the phone with, my dad talking about them with them with different things, utters opinions, strong opinions sometimes being uttered between people in the car. So it's always quite interesting. But how does this fit into the urea cycle? Okay. So, ordinary or we start with ornithine, our carrier molecule. We're going to say Carpooling Car carbamoyl phosphate, carp. Citizen is citrulline. And if we look, these 3 are all part of reaction 1. Here goes 1. Next, we have, aspires, arrange, success, aspartate, aspires, arranged. Here we're talking about argininosuccinate. Success, we have succinate involved. R succ, argininosuccinate. Fuels arguments, fuels fumarate. Arguments arginine. Again, if we go here, this is reaction 2, which is our aspartate. Reaction 2 is our aspartate, and then argininosuccinate. Reaction 3 is fumarate and arginine. And then finally, reaction 4 utters opinions. We have urea and ornithine being regenerated for reaction 4. Remember, arginine, we utilize the enzyme Arginase that helps to produce urea as a product that we excrete in urine and then regenerates ornithine. So, again, utilize this memory tool, think about a cabbie, picking up different fares, hearing interesting conversations, hearing opinions being exchanged, maybe between the cab driver and the passengers, or the passengers amongst one another. Right? So this helps to frame the different types of metabolite names within the urea cycle.
