In this example, we need to match each of the following statements with the correct polysaccharides. So option 1, we have amylopectin and glycogen. Option 2, we have just glycogen. And option 3, we have cellulose.
Alright. So for the first statement, it says it's an unbranched polysaccharide composed of beta-1,4-glycosidic linkages. When it comes to amylopectin and glycogen, they have branching groups. They have alpha-1,6 branching groups, so they would be out. That means the answer is option 3. Cellulose is an unbranched polysaccharide, and also it's the only one with beta linkages.
For the next one, a polysaccharide that is stored in muscle tissues. Alright. So, where do these polysaccharides come from? And when we think about it, we'd say that glycogen has to be the answer here because glycogen's source is animals, and we're talking about muscle tissues. We wouldn't talk about muscle tissues with plants here, we talk about fibrous tissue. That's different. So here, this would have to be option 2.
And then finally, this is a polysaccharide containing alpha-1,4 and alpha-1,6 glycosidic linkages. This is true of both amylopectin and glycogen. So option 1 would be our final answer here. So this is how we would basically match each of the statements with the correct polysaccharide.
