Okay, So this problem wants to know what happens when a photo system absorbs light. So a photo system, as you see I've drawn here, is just gonna be a cluster of pigments. So, for example, chlorophyll in plants, cells that absorbs light energy. And so, as we talked about in problem eight and light dependent reaction B, it's I liquid membrane is going to get electrons from water molecules that are inside the cell. So it's gonna get these electrons, and those electrons are gonna go up to a photo system and photo systems. What they do is absorb energy from lightwaves. So it's gonna absorb that light energy, and it's actually gonna transfer it and put that energy into this electron and energize it. And so then, once the electron is energized, is gonna move to the top of the photo system, the outside of the thigh liquid membrane, and then drop down that electron transfer chain to release energy like we talked about in problem me also. And so what? This So it's going Teoh release electrons is what the photo system will do. And when it says in, um, answer, see the special pair, Um, what it's going to mean by that. Is the special pairs, actually, maybe that part on the right, where the electrons going through? So that's squared off part, um, this circle, this part of the photo systems was gonna be absorbing the light. And then it's special pair, which you see squared off now is going to be releasing that Electra.
