Same goes for nearly all cellular processes. Metabolism is virtually impossible to define as a series of discrete elegant deterministic procedural steps and properties. Same goes for insulin, and all other hormones. You can't even try to think of something like insulin as massive polynomial function where you might eventually understand all of the variables involved and how they affect said function. In fact the function could completely change at any time depending on other esoteric confounding factors in the body. It's absolutely insane. In fact almost all biological functions in the body can be described as trillions of chemicals and chemical pathways interacting in infinitely complicated ways that just so happen to occasionally result in enough homeostasis to support the macroscopic survival of said organism because of a sloppy brute force evolutionary system that took centuries to unfold.
