"### Michaelis-Menten Enzyme Kinetics\n",
"[Michaelis-Menten](https://en.wikipedia.org/wiki/Michaelis%E2%80%93Menten_kinetics) kinetics describes how quickly a reaction happens when an enzyme—a type of molecule that speeds up processes in the body or other reactions—interacts with other molecules. Initially, as the amount of molecules $x$ increases, the reaction speed, $y$, increases. But at a certain point, adding more molecules doesn’t increase the speed much because the enzyme is already working as fast as it can.\n",

"Two key things come from this: the maximum speed the enzyme can reach $V_{max}$ and the concentration level at which it’s working at half that maximum speed $K_m$. These insights help us understand efficiency and limitations, which is valuable for making decisions in fields like drug development, where knowing an enzyme's limits can guide dosage or predict interactions.\n",
