I'll show you on the next slide, it's the release of goblet cells. Another type of signal is signal arrives, the cell then has to synthesize a bunch of new proteins and respond to that signal, transcription is required, if the transcription is required things slow down, okay, so this is a slow type of signal over here. For example, skin cells that have to fill in a wound, okay, so you cut your finger with some paper or something like that, the skin cells nearby have to and fill in that injury and so Buy Terpenes this is not going to happen instantaneously, right, you know that it takes a couple of days for the paper cut to heal, right, it doesn't happen instantaneously. It doesn't have to happen instantaneously for that matter, and so this is a slow type of cell signalling. Commonly there's both a slow and fast response. For example, a response to insulin, so the insulin won't rise the cell immediately start responding using the glucose transporters that we discussed when we talked about biology a few weeks ago. But in addition, the cell has to respond to this insulin by synthesizing new proteins and having a slow response.

So this hybrid is also a very common mode as well and so we're going to see these three different scenarios play out. The first scenario is this business about, so for example agonists buys a stimulates intestinal goblet cells to spill out in a rapid response, okay, so this is you, you're eating something, you counter something that's bitter like buys a and you have to immediately respond to that, you know, your stomach doesn't like bitter stuff. And so the stomach and the intestine respond by secreting all this, True Terpenes we've talked about the structure of, it's and that helps smooth the passageway and get rid of this bitter-tasting compound. Okay, so here are the goblet cells over here, they've already stored up all the, okay, it's already over here so as soon as you immediately start spewing out the, it flows out into the intestines and it's already been pre-synthesized.

So, no DNA transcription is required, you've got an immediate response, okay, now I'm also trying to systematize self signalling so also on the level of systemization, cells can either be talking to each other, to different kinds of cells or they could be talking to the same class of cells. And these two different classes of cell signalling are referred to like either or is communication between cells of the same type, okay, so if those goblet cells are stimulating each other that would be, if however, Terpenes for sale they depended on a different class of cells to stimulate them that would be, okay, make sense. Okay, now it turns out that within all of the biology there's really only seven different types of cell signalling, okay, and I want to make this point, this is super duper important because when you pick up the literature in cell biology and signalling it's insanely confusing and complex. Cut through all that complexity, all that matters is that there are seven different types of cell signalling, if you learn these seven different types of cell signalling you will understand all of the different kinds of pathways that are written about in the current literature, okay. And one of the problems with -- okay, so I'm starting to get off the track, I can't resist. Okay, so one of the things that makes this difficult is.
