Question

1. the monomer of a nucleic acid is a nucleotide. label it on the diagram at right. 21. nucleotides are monomers/building blocks of a larger molecule used to store heredity information called _. 22. _ is a single nucleotide (no polymer) that is used for cellular energy. 23. how are nucleic acids related to living things? in other words, what is their role in life? proteins 24. proteins are made up of subunits/monomers called amino acids. explain how there are thousands of different kinds of proteins, but only 20 different amino acids. for each description below, determine if it best matches carbohydrates, lipids, nucleic acids or proteins. write a “c” for carbohydrate; “l” for lipid; “p” for protein* or “na” for nucleic acid. 25. a quick source of energy. 26. helps build bone, muscle, skin, and tendons. 27. stores genetic information. 28. essential for the development of the body systems that communicate via hormones. 29. composed of glycerol and fatty acids. 30. enzymes are made of this particular organic compound. 31. plays a critical role in the structure and function of dna. 32. using food as an example, steak would be primarily made of this organic compound. 33. using food as an example, bread would be mainly composed of this organic compound. 34. using food as an example, butter would mainly composed of this organic compound.

Explanation:

1. Nucleic acids that store heredity information are DNA and RNA, made of nucleotides.
2. ATP (adenosine - triphosphate) is a single - nucleotide energy molecule.
3. Nucleic acids (DNA and RNA) store and transmit genetic information, which is crucial for the development, function, and reproduction of living things.
4. Different proteins are formed by different sequences and combinations of the 20 amino acids.
5. Carbohydrates are a quick source of energy, so the answer is C.
6. Proteins help build bone, muscle, skin, and tendons, so the answer is P.
7. Nucleic acids store genetic information, so the answer is NA.
8. Hormones are related to lipids in the context of steroid hormones, so the answer is L.
9. Lipids are composed of glycerol and fatty acids, so the answer is L.
10. Enzymes are proteins, so the answer is P.
11. Nucleic acids play a critical role in DNA structure and function, so the answer is NA.
12. Bread mainly contains carbohydrates, so the answer is C.
13. Butter is mainly composed of lipids, so the answer is L.
14. Butter is mainly composed of lipids, so the answer is L.
