Question

plant - based foods - like potatoes - contain starch which is made of connected sugar molecules. the most common sugar molecule used by humans is the glucose molecule shown below. what patterns do you notice when you compare this sugar molecule and the amino acid molecules from the previous page. how are they similar? (note: each question is actually worth 0.3 points) a. true (this is how they are similar) b. false (this is not how they are similar) 11. (0 points) they contain all the same elements. 12. (0 points) they contain atoms that are joined by bonds. 13. (0 points) they have the same number of atoms of each element. 14. (0 points) they contain carbon, hydrogen, and oxygen. 15. (0 points) glucose and amino acids are both monomers that can be joined to form long polymers. what patterns do you notice when you compare this sugar molecule and the amino acid molecules from the previous page. how are they different? (note: each question is actually worth 0.3 points) a. true (this is how they are different) b. false (this is not how they are different) 16. (0 points) amino acids contain nitrogen while glucose does not. 17. (0 points) glucose contains a ring of atoms while none of the amino acids do. 18. (0 points) their atoms are bonded in a different arrangement. 19. (0 points) glucose has an equal number of c to o, while amino acids may have less o in relation to c. 20. (0 points) glucose forms polymers while amino acids do not.

Explanation:

1. Amino acids contain nitrogen, while glucose only has carbon, hydrogen, and oxygen. So they don't have all the same elements. Answer is b. False.
2. Both are molecules, so they have atoms joined by bonds. Answer is a. True.
3. Different molecules have different numbers of atoms of each element. Answer is b. False.
4. Glucose and amino - acids both contain carbon, hydrogen, and oxygen. Answer is a. True.
5. Glucose is a monomer for starch and amino acids are monomers for proteins. Answer is a. True.
6. Amino acids have nitrogen and glucose doesn't. Answer is a. True.
7. Glucose has a ring - structure, not all amino acids do. Answer is a. True.
8. Their atomic bonding arrangements are different. Answer is a. True.
9. Glucose has a 1:1 C to O ratio in its empirical formula, amino acids don't. Answer is a. True.
10. Amino acids form proteins (polymers) and glucose forms starch (polymers). Answer is b. False.

Answer:

1. b. False
2. a. True
3. b. False
4. a. True
5. a. True
6. a. True
7. a. True
8. a. True
9. a. True
10. b. False
