Question

1. you are walking down the tough streets of new jersey, and suddenly you feel the need to run away from someone who is accosting you! your muscles keep a form of energy stored just for these emergencies. what macromolecule stores energy in the muscles? a glucose b. galactose c. starch d glycogen e. chitin 2. a polysaccharide is formed when many monosaccharides are joined together by a. dehydration synthesis reaction b. a hydrolytic reaction c. a hydrolysis reaction d. a and b e. b and c 3. the main source of energy for cells is a. sucrose b. glucose c. fructose d. galactose e. maltose 4. potatoes have a large amount of a. protein b. lipids c. nucleic acids d. wax e. carbohydrates

Explanation:

1. Glycogen is the energy - storing macromolecule in muscles. Glucose is a monosaccharide, galactose is also a monosaccharide, starch is the energy - storage in plants, and chitin is a structural polysaccharide.
2. Polysaccharides are formed from monosaccharides by dehydration synthesis reactions. Hydrolytic and hydrolysis reactions break down polymers.
3. Glucose is the main source of energy for cells. Sucrose, fructose, galactose, and maltose are also sugars but not the main energy source for cells.
4. Potatoes are rich in carbohydrates, especially starch which is a type of carbohydrate.

Answer:

1. d. Glycogen
2. a. dehydration synthesis reaction
3. b. Glucose
4. e. Carbohydrates
