Can somebody check if my answer is rght? Thank you

Complex carbohydrates

Indicate whether each of the following statements about polysaccharides is True or False.

1. Polysaccharides are long polymers made of many nucleotides that have been joined through dehydration synthesis. False
2. Cellulose is the main storage polysaccharide in plants while glycogen is an important storage polysaccharide in many animals. False
3. Both starch and glycogen are composed of α-glucose subunits. True
4. Starch is composed of amylose and amylopectin, which are unbranched and branched chains of α-glucose subunits, respectively. False
5. Like amylopectin, glycogen is insoluble in water, but it has a longer average chain length and fewer branches. True
6. Although some polysaccharides are used to store energy, others serve as structural material for cells. True
7. The principal structural polysaccharide in plants is starch. True
8. Cellulose is composed of a long, branched chain of β-glucose subunits. True
9. The starch-hydrolyzing enzymes produced by most organisms cannot break the bond between two α -glucose subunits because they only recognize β linkages. False
10. Chitin is a structural polysaccharide found in the exoskeleton of arthropods and the cell wall of many fungi. True

What is the overall summary of this paragraph? Do you think that the structure of the two components of starch has any thing to do with the study results? Why? Why not?

Guezennec et al. (1993) studied the difference in carbohydrate oxidation during exercise when amylose and amylopectin were consumed prior to exercise. Amylopectin was oxidized more quickly during exercise than was the amylose. Goodpaster et al. (1996) tested whether high amylose or high amylopectin foods fed prior to endurance exercise had different effects on metabolism or performance when compared to placebo or glucose feedings. A lower glycemic response was seen for both starches compared to glucose during the 30 min prior to exercise. However, in contrast to the results of Guezennec et al. (1993), the starches did not differ from one another in their glycemic responses in this pre-exercise period. Furthermore, all carbohydrate treatments increased the reliance on carbohydrate as a fuel during exercise. When compared to the placebo, the high-amylopectin starch was as effective as the glucose feeding in enhancing endurance performance but, in spite of similar glycemic effects of the two starches, the increased amount of work done during the 90 min performance test when the high-amylose starch was consumed was not statistically significant from the placebo. The authors felt that the lower digestibility of the high-amylose starch contributed to its reduced benefit on exercise performance. This study did not support a benefit of a lower glycemic food, i.e., starch, over a higher glycemic food (glucose) fed prior to exercise.

Organisms must use macromolecules that have properties to match their functional requirements. Choose the appropriate macromolecule whose properties meet the requirements. Note: a macromolecule may be used more than once.

Cellulose, Chitin, DNA, Fat, Glycogen, Lactose, RNA, Starch
