Name the types of chemical reactions that tend to be found in anabolic pathways.

Question

Accepted Answer

All right. Hello everyone. So this question is asking us which of the following biochemical reactions occur in anabolic pathways. So here we have four different reactions which we'll discuss individually later on. And four different answer choices labeled A through D proposing which statements or rather which reactions are true of anabolic pathways. Option D says all of these. So first and foremost, we call it anabolic pathways or anabolism is one of the ways that we can classify metabolism or metabolic pathways as a whole metabolic reactions. So metabolism can be divided into two distinct categories. So it encompasses catabolism or catic reactions, catic pathways as well as anabolism. And now is so that's anabolic reactions, anabolic pathways. So what's the difference between them? Well, catabolism refers to taking big complex starting materials and breaking them down into smaller simpler final products. This oftentimes releases energy. Now, by contrast, in anabolism, you take smaller simpler starting materials, building blocks, so to speak, and combine them to produce a bigger, more complex final product. This requires the input of energy typically. So with this context in mind, let's go ahead and go through each of these reactions. Now, according to the definitions described here, anabolic pathways are ones that construct more complex molecules from simpler precursors. So let's keep that in mind starting off with number one here, which is condensation. So what is condensation? Right, recalled condensation describes the joining of two molecules and often times as a consequence of this new bond being formed to join the two molecules together. A small molecule is removed as a result, oftentimes this molecule is water, which is why it's called condensation. Now, once again, notice how we're taking two separate molecules and combining them to create a larger product because this is characteristic of an anabolic pathway. Condensation is going to be correct here, it is a correct answer. So number two reaction to is hydrolysis. Now, what is hydrolysis? Well, hydrolysis, specifically the phrase here lysis refers to the breakdown of something. So during hydrolysis, what you're doing is breaking a bond using water. So you're adding water to your starting material to break a chemical bond. So if we're breaking a bond, we're taking a larger starting material and creating a smaller product. So, hydrolysis is not part of in anabolic pathways. It's not part of anabolic pathways because it's actually associated with catic pathways. Number three, on the other hand, is reduction. Now, reduction, if you recall refers to the gain or acquisition of electrons or hydrogen atoms. Now recall that reduction reactions are actually considered part of anabolic pathways. An example of this is the biosynthesis of fatty acids or in the Calvin cycle of photosynthesis. So, reduction is a correct answer. That's number three. So number four is carboxyl solution. So what is carboxyl? Well, recall that it is the addition of a carboxyl group to your starting material that's co O negative. So notice the phrasing here, we are adding something, adding a functional group to a starting material, we are taking a starting material and making it bigger by adding something else to it and creating a new bond. This is characteristic of an anabolic pathway which means that carboxyl number four is the correct answer. So there you have it of the reactions being described here, condensation reduction and carboxyl that's 13 and four are correct, which means that B is our final answer. And so with that being said, thank you so very much for watching. And I hope you found this helpful.
