What holds cellulose molecules together in bundles large enough to form fibers? a. the cell wall b. peptide bonds c. hydrogen bonds d. hydrophobic interactions

Video transcript

Hello everyone. And in today's video we have to follow in problem. So which one of the following is not true regarding cellulose. Remember that we're looking for the incorrect statement and more answer choices. So I want you to recall from previous videos some of these general properties are just the main definition of cellulose in terms of its structure. And cellos turns out that it is a policy aka ride made up of glucose monomers because of these. This little Los is going to share many of the same properties that glucose has because it is made up of glucose. So now that we know this information, let's jump straight into the problem so that we can start solving it beginning by answer choice a We have that glucose molecules are held together by glue like acidic bonds to form settlers. And this is exactly what a policy security is. Is many of these glucose molecules held together by these godlike acidic bonds. And this entire structure is cellulose. So it is a correct statement. Since we're looking for the incorrect statement, we're going to be canceling this out. Moving on, we have the cellulose is a structural policy aka ride What we already saw that here in our definition is a policy Zachary made up of glucose monomers. So this is actually correct as well and we will cancel it out. Then we have options. See cellos forms the cell walls of plants. This is actually a correct statement because cellos is present in the cell wall of plants as a structural support. So it is what brings structural support to this cell wall of the plants. And then finally this left side with. Andrew choice D settle loads is a highly hydrophobic molecule. Now, if you remember anything about hydrophobic molecules are usually non polar. Now we have that this settle Los is mostly made up by glucose molecules. And if you remember the structure of these glucose molecules, they have a lot of O. H groups because their carbohydrates, these ohh groups are polar, making glucose and as a result, settle Los hydra filic or likely to interact with water because water is also a polar. So these glucose molecule will not be hydrophobic, it will be hydro filic or this little molecule will not be hydrophobic will be hydra filic. And that will make d or final answer to a question. So, thank you very much for sticking around until the end of this video. I really hope it helped you.
