Document Summary

Carbohydrates the nature of carbs is composed of carbon, hydrogen and oxygen. Alterations in atomic arrangements make molecule distinctly different. 2 to 10 sugars bonded chemically: disaccharides very common. 3 to thousands of sugars linked together. Example glycogen in muscle and liver 1 days diet 2000 kcal. During training athletes may increase up to 70% Energy source catabolism of blood glucose and glycogen. The higher the intensity of the exercise the greater reliance of cho as a fuel. Protein sparer when carbohydrates are depleted, proteins increasingly converted to glucose by gluconeogenesis. Metabolic primer glycogen depletion causes fat mobilization to exceed its oxidation result in in increased ketone formation. Ketones are produced when the body burns fat for energy or fuel. They are also produced when you lose weight or if there is not enough insulin to help your body use sugar for energy. Without enough insulin, glucose builds up in the blood.

Charts and tables are tools we use in science to break down information analytically and present data in an organized manner. It is a beneficial strategy for learning about and organizing scientific material, which we will be using often in this class. Make sure that you are detailed, thorough, and specific in your responses. Explain yourself clearly. Do not list a word or brief phrase without explaining what it means. For example, if you list diabetes for carbohydrates, make sure you explain how carbs are associated with diabetes. Don't leave the reader to make that connection for you. Also, make sure you provide APA-style references for each of your so

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 Î±-glucose subunits. True
4. Starch is composed of amylose and amylopectin, which are unbranched and branched chains of Î±-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 Î²-glucose subunits. True
9. The starch-hydrolyzing enzymes produced by most organisms cannot break the bond between two Î± -glucose subunits because they only recognize Î² linkages. False
10. Chitin is a structural polysaccharide found in the exoskeleton of arthropods and the cell wall of many fungi. True
