What is the relationship between photosynthesis and respiration?

Question

Accepted Answer

Welcome back, everybody. Here's the next question, which statement correctly describes the relationship between the products of photosynthesis and the reactants of cellular respiration. So we have four different answer choices A through D rather than reading them all through twice. Let's think about these two processes and then evaluate our statements. So photosynthesis is an anabolic process. So it's a process of building up larger molecules, more complex molecules from small molecules. So we're going from small molecules. So we go from, in this case, we're going to supply, excuse me or the large molecules supplying. It's an anabolic process that produces glucose and we need a carbon source for that and we need energy. So we recall that in photosynthesis, our carbon source will be co2 now not writing a balanced equation here, just the things that go into it. So carbon dioxide we have right there are prefixed photo reminding us that we use light energy. And in addition, we need water and this will yield glucose and oxygen 02. Now, in cellular respiration, this is the reverse. It's a catic process that breaks down glucose instead of yielding it. So we start with glucose, glucose is getting oxidized. We need some oxygen to do that and it's going to yield, it's gonna break down the glucose that will yield energy in the form of a TP. It will yield carbon dioxide since you've broken apart the glucose molecule and it will yield water. So our question asking us about products of photosynthesis. So glucose and oxygen and the reactants of cellular respiration, glucose and oxygen. So let's evaluate our statements now that we have thought this through a, the products of photosynthesis are sunlight and carbon dioxide which are used in cellular respiration, but sunlight and carbon dioxide are the reactants of photosynthesis. So A is incorrect. B says the products of photosynthesis are glucose and oxygen. That is correct, which are reactants and cellular respiration and that is correct. So, so B will be our answer just to be thorough. Let's look at our other answer. Choices. C says the products of cellular respiration are used as reactants and photosynthesis without any by products. Well, it is true that the products of cellular respiration are used as reactants. So, carbon dioxide and water are products of cellular respiration and reactants and photosynthesis, but there's other by-product. And in addition, this is not the correct relationship. Our question asks us for the relationship between the products of photosynthesis and the reactants of cellular respiration, right? Not correct relationship. So, cross that choice, C and joy D says the products of cellular respiration include glucose and sunlight which are necessary for photosynthesis. I hope we don't think that cellular respiration produces sunlight. We will cross this out. Um So that one's just wrong. I don't even need to go into that. But our, again, our answer here for a statement that correctly describes the relationship between products of photosynthesis, reactants of cellular respiration. It is choice B that the products of photosynthesis are glucose and oxygen which are reactants and cellular respiration. See you in the next video.
