Tight junctions perform two distinct functions: they seal the space between cells to restrict paracellular flow and they fence off plasma membrane domains to prevent the mixing of apical and basolateral membrane proteins.

Questions junctions in particular the type of junction that allows the movement of module seuin from cell to cell. And the answer is B. Gap junctions are the junctions that basically form passageways or connections between neighboring cells that allow molecules of different sizes to pass through. So, um, thes are basically connections or passageways between the planets MMA of each cell, so passageways. And there are proteins called connections that connect one cell from the other. There. Different kinds of connections in Exon's and they ah, different size and kinds of molecules through so gap junctions, air passageways between a brain cells from there to other kinds of junctions. The book talks about their tight junctions, Um, tight junctions. The name says it all these seal neighboring cells together, and ah, this prevents, um, anything completely molecules from sort of ginning between them, so it's seal cells together. So if we have to cells like this right, the use a different color. The tight junction is here, right, and that prevents anything from sort of leaking down between the two cells. And then finally there decimus sums another ah way that sells, ah, interact with each other. Ah, and test Newsom's bind or attach cells. Ah, and they do it either to neighboring cells. So they're just physical connections or to some kind of extra cellular matrix. The goal here is to hold cells in place. So the answer. The question is gap junctions, because gap junctions air passageways that allow molecules like ions to move from the side of plasm of one cell to the side of class of another. But we also have tight junctions, which steals tells together and Desmond cells, which bind or hold cells into place.

So at here. Instructions are a type off cell junction that is found in epithelial cells and that connects the membranes of them. And these air usually found close to the app ical surface of the skin just below the tight junctions that make our skin watertight. And this question is asking us specifically about their role in controlling cell shape. And it asks, Assess what Associate ID? Interest, cellular structure and proteins are involved in this role to the mechanism by which adherence junctions can control cell shape is that they are connected to an intracellular belt of acting and rice Annville mints that acts as a cable to control cell shape and hold its tension. And, as you can guess from the acting and bison, we are dealing with the sido skeleton here, so the associated interest cellular structure would be the Seidel skeleton, and the proteins involved would be acting, and Maya said

Prayer in this question. We are being asked outside Lazar, move one cell. You communicate directly to the side pleasant off another self. So the key word here is cytoplasm to sidle last any occasion. So let's just get out like that means that you have what's so two, another cell. And we want the cytoplasm off this cell to communicate to the side plaza off this cell without any three years. And the only way that happens is the essential of tunnels between Easter cells. And there was no last month memory for the communicators for be signally molecules to have two faster. So that way you get this is an area where a messenger of Allah you would just flow directly from one side plaza to another class. So now let's look at our answer choices. Here. Joyce is his Hazel Johnson's. And as their names suggest that these junctures help sells it here to each other, that is, to stick together. They accomplish this through integral proteins called get hearings. It's basically excellent Velcro between cells, but, uh, this is no, this is this one has no link between the two of em breaks. So choice a is in forever. Hi. Junctions are a type of adhesion junctions, kind of like the the Velcro situation here that we have with the appearance. You have a giggle kind of protein stitching the two membranes together. Eso This night A junction also does not allow for communication between the two sides. So, as I said, people were injured. Judges are like Velcro junctions, like zippers holding the team members to get choice. See is gap jumpers. Gap junctions Army When channel proteins, right? These are channeled. Brody's jail broken through the members of two different cells joined together. General Brody's, as the name implies, who? He's a channel across the membrane, which allows for passage of molecules across the memory. So when the Channel provisional Themselves Lineup, they formed this channel tunnel that we were talking about so that a molecule can essentially travel from side of plasm to silent as um so the answer is ghat junctures

Since Guatemala kills cannot pass through the membranes himself. Therefore, um, they did Klopp foreign last from a channel within the past Draymond green in other toe allow they movement often water molecules between the extra cellular matrix in the interests illness based Tom. To do so, Ecuadoran must be and see Bessie just like the forceful it pits off the plasma membrane. The sound tough It's are asking Botham rt Halperin what contain trashed? Oh, Pola. And we know it s it's, uh another toe interact 50 loquacious environments On the other hand, the transmission brain region off the equal pour in Oh which was interacting with 50. Um, plasma membrane will contain man Pola and we know assets so that, um, this vision can indirect 50 forcefully tills We'll be in Cuba off the cop or in China must come team um, hydro filling and we know essence last to allow for the interaction half they want the molecules in the passage through this channel. So this on the key feature does after produce shape in the going got characteristics off his eminent visits
