Okay, so we&#x27;ve all heard that photo soup. This is consumes carbon dioxide and produces oxygen. Okay, so where does this oxygen actually comes from? So let&#x27;s look at the, uh, overall chemical equation for photosynthesis is what you have is sealed too, plus h 20 plus energy, and you are producing glucose and oxygen. So you are consuming carbon dioxide and you are producing oxygen. So where does that oxygen comes from? Come from? Well, actually, during the light reactions, what happens is that water is split into h pluses and into highnesses, and you need to split two waters in order to make four hydrogen sze and 102 Okay. And this is basically the oxygen that is released on this side if the carbons in carbon dioxide are incorporated into the glucose by using the energy from the sun. Okay, so the oxygen given off by photosynthesis comes from water. Okay. Not from carbon dioxide. Glucose is a product, so glucose cannot provide the oxygen. Okay. And are you BP? Are you B P is an intermediate in the cow. Been cycle or the dark reactions. Okay, So are you. BP basically gets regenerated in the Calvin cycle. Okay. And this is not where the oxygen comes from because this isn&#x27;t a lot in the dark reactions. The oxygen actually comes from water when water gets split in the light reactions, so the answer is a

Okay, So this problem wants to know where the atoms and oxygen molecules that are released. Certain photos since this, they&#x27;re gonna come from. And so we&#x27;re actually gonna get those from that very first stage, the light dependent reaction of photosynthesis. And so, as we talked about in problems nine and eight, you have water molecules in the file coId and those using light energy. We&#x27;re gonna break those water molecules up the H 20 we&#x27;re gonna break it apart on what it&#x27;s gonna break into his two hydrogen ions, and I on just means it&#x27;s charge. And that&#x27;s where we get those electrons from that go through the electron transfer chain. And then the other thing is gonna break into is an oxygen molecules. So that late energy is gonna break all those bonds part and you&#x27;ll get to hydrogen ions and then one oxygen molecule. So then, when another, um, water molecule is in the cell and gets broken up by that light energy, you&#x27;re gonna get the two hydrogen ions again. But then you&#x27;re also gonna get a second oxygen, and those who are gonna come together to form that 02 that&#x27;s then going to leave the cell and go into the atmosphere, so yeah, leave. So I&#x27;m going to atmosphere. So, like I said, we&#x27;re gonna get those oxygen molecules from that water, the H 20 molecule. And so that&#x27;s gonna be answer C.

the Adams in the Austrian molecules that get released during photosynthesis come from which of the following Well, um, in their light dependent reactions. Once the four system to gives off its electron, it needs an electron, so it uses water and it&#x27;s blitz that water and it forms oxygen. And so the splitting off the oxygen of the water essentially gives that oxygen. It produces oxygen. And so the correct answer here is sea water, because the water will also donate its electron to the forest. So it does both simultaneously. Thank you for watching, and I hope this helps.

oxygen is given off by plants, and does it come from a The deep e, the deep. See the chlorophyll, a e p. Eagle or e water so the oxygen comes from e water. Bring the light dependent reactions. We get photo license, so bring light into a light dependent reactions. Photons hit or if l. A. R. If l. A. Loses electrons on DKNY&#x27;s to replace them, we get those electrons from photon isis of water. But as a size product, we also get an atom of oxygen. Water is broken down into two protons. Two electrons andan oxygen atom. So, yes, it&#x27;s E.

Sydney Mastalerz · Answer

Okay, So this question wants to know what the energy sources that drives the process of photosynthesis in plants. And so our options that it gives us our sunlight, sugars, oxygen and carbon dioxide did shoot. So what we know about sugar&#x27;s and that sugars are actually going to be what the plants make using the process of photo senses. But they won&#x27;t be the energy driving it. And then with oxygen and CO. Two carbon dioxide, those air going to also be things that the plants use during photosynthesis in order to make those sugars. But they will not be the energy driving it. So the energy driving the process of photosynthesis in plants is going to be the light energy it gets from suddenly, and that will be the answer.

Aditya Sood · Answer

most of the carbon dioxide that plants use for photosynthesis comes from blink glucose, rainwater, the Atmosphere and Pharrell Isis. Well, the product that they&#x27;re trying to make is glucose, so it doesn&#x27;t make sense that they would use carbon dioxide from glucose to make Wilco&#x27;s, uh, Moreover, glucose is not contained carbon dioxide, so they get most of their carbon dioxide from the most readily available source our atmosphere. So the correct answer is b the atmosphere. Thank you for watching, and I hope this help.
