Question
- the properties and functions of molecules are determined by how the subunits in a polymer are joined together.
1 how many glucose monomers are shown connected together in starch?
2 which carbohydrate is made up of 1 linear chain? starch, glycogen, or cellulose?
3 which carb is made up of 3 linear chains connected together?
4 which carb is made up of 1 polymer with a few branches?
Question 1: How many glucose monomers are shown connected together in starch?
Step1: Observe the starch structure
Looking at the diagram of starch, we can count the number of glucose monomers (the hexagonal units) connected in the chain.
From the visual, we see that there are 5 glucose monomers connected in the starch chain shown.
Step1: Recall the structures of each carbohydrate
- Starch: Can have both linear (amylose) and branched (amylopectin) forms, but the linear form is one type of starch structure. However, looking at typical diagrams, cellulose is a linear chain of glucose units, glycogen is highly branched, and starch (amylose) is linear but sometimes starch diagrams may show a mix. Wait, re - examining the diagram:
- Starch diagram: The starch shown has a linear chain (the straight chain part). But wait, cellulose is also linear. Wait, no, in the given diagram:
Looking at the three structures:
- Starch: The diagram shows a linear chain (the straight line of hexagons) and maybe some branching? Wait, no, the first diagram for starch: let's check the number of chains. Wait, the question is which is made up of 1 linear chain.
- Cellulose: The cellulose diagram shows multiple linear chains (three parallel linear chains).
- Glycogen: The glycogen diagram shows a highly branched structure.
- Starch: The starch diagram (the one with the potato) shows a linear chain (the straight line of glucose monomers) and maybe a branched part? Wait, no, the question is "made up of 1 linear chain". Wait, maybe the diagram shows starch as a single linear chain (amylose), glycogen as branched, and cellulose as multiple linear chains. So from the diagram, starch (the linear part) or cellulose? Wait, no, let's re - look. The cellulose diagram has three parallel linear chains. The starch diagram has a single linear chain (the straight line of glucose units) and maybe a branched part? Wait, the question is "which carbohydrate is made up of 1 linear chain". So among starch, glycogen, cellulose:
- Glycogen: branched, so not linear.
- Cellulose: multiple linear chains (the diagram shows three parallel lines of glucose units).
- Starch: the diagram shows a single linear chain (the straight line of glucose monomers). So the answer is Starch? Wait, no, maybe I got it wrong. Wait, actually, amylose (a form of starch) is a linear chain, amylopectin (another form) is branched. Cellulose is a linear chain but usually in microfibrils with multiple chains. Glycogen is highly branched. So if the diagram shows starch as a single linear chain, then starch. But maybe the diagram for cellulose has multiple chains, glycogen is branched, and starch has one linear chain. So the answer is Starch? Wait, no, let's check the diagram again. The starch diagram: the straight line of glucose units (let's say 5 units) is a linear chain. The cellulose diagram: three parallel lines of glucose units (so multiple linear chains). Glycogen: a branched structure. So the carbohydrate made up of 1 linear chain is Starch? Wait, maybe the answer is Cellulose? No, cellulose has multiple chains. Wait, maybe the question is which has one linear chain (not multiple). So Starch (amylose) has one linear chain, cellulose has multiple linear chains, glycogen is branched. So the answer is Starch? Wait, I think I made a mistake. Let's re - read the question: "Which carbohydrate is made up of 1 linear chain? Starch, glycogen, or cellulose?"
From the diagram:
- Starch: The diagram shows a linear chain (the straight line of glucose monomers) and maybe a branched part, but the main linear chain is one.
- Glycogen: Branched, so no linear chain (or highly branched, not a single linear chain).
- Cellulose: Multiple linear chains (three parallel lines in the diagram).
So the answer is Starch? Wait, no, maybe the answer is Cellulose? No, cellulose has multiple chains. Wait, perhaps the diagram is different. Let's assume that in the…
Step1: Observe the diagrams of each carbohydrate
- Starch: Has a linear (and maybe branched) chain, not three linear chains.
- Glycogen: Branched structure, not linear chains.
- Cellulose: The diagram of cellulose shows three parallel linear chains of glucose units connected together (maybe by hydrogen bonds or other interactions). So by looking at the diagram, cellulose is made up of 3 linear chains connected together.
