What is the difference between catabolism and anabolism?

Question

Accepted Answer

All right. Hello everyone. So this question is asking us which of the following statements correctly differentiate catabolism from anabolism. Here we have four different entry choices labeled A through D and we're going to discuss options A through C in greater detail later on in this video, but option D simply says none of the above. So with this being said, let's go ahead and distinguish between the two, what are cat bolic pathways and what are anabolic pathways? Well, first, it's important to understand the general definition, right. Catabolism refers to metabolic pathways in which oops in which larger reactants are converted into smaller products. So once again, catabolism involves breaking down molecules into smaller products. On the other hand, anabolism or anabolic pathways refer to the opposite. It's taking smaller reactants, smaller starting materials and combining them together to create larger products. Now, from this general definition, we can infer a few different details about both types of pathways, metabolism because it involves the breakdown of larger substances into smaller ones, generally involve the release of energy. So catic pathways can be said to provide energy to the cell. On the other hand, because anabolic pathways require building larger products from smaller reactants or smaller building blocks. Energy is required or rather they consume energy, anabolic pathways, consume energy. But even though anabolic pathways consume energy, they're still necessary to synthesize necessary components relative to irrelevant for the maintenance of the cell. For example, protein synthesis is an example of an anabolic pathway. An example of a cab bolic pathway is glycolysis and so from here, because catic pathways involve the release of energy. Oftentimes catic pathways involve oxidation. So, catic pathways often involve oxidation where molecules that have been oxidized, reduce or release energy. As a result. On the other hand, anabolic pathways oftentimes involve reduction. In other words, molecules are being reduced and energy is consumed to make that happen. So from here, let's go ahead and talk about options A through C. I'm just going to move this text that I wrote earlier just to improve the spacing a little bit. So from here, let's talk about A through C option A says that catabolism involves oxidative pathways. Whereas anabolism involves reductive pathways. This is correct because this is something that we talked about a few moments ago. Moving on to option B, it says that catabolism involves the process of utilizing energy. While anabolism involves the process of supplying energy, this is not correct because it's actually the other way around. Right. Catic pathways involve supplying energy and anabolic pathways require the consumption of energy or the use of energy to create larger products from here, option C says that metabolism involves a constructive metabolism. Whereas anabolism involves a destructive metabolism. This is not true because this is also the other way around. Right. Catabolism involves the breakdown of larger reactants into smaller products, which is a destructive pathway. Anabolism is a constructive pathway because you are constructing larger products from smaller reactants. So just to reiterate our answer is going to be option A in the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
