BIOD 101 FINAL EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED)a. Name the three parts of a nucleic acid nucleotide. b. What are the particular types of each of these that are found in DNA and what are the corresponding types that are found in RNA? Answer a. sugar, phosphate group, nitrogenous base b. DNA- deoxyribose- phosphate group- adenine, guanine, cytosine, thymine RNA- ribose -phosphate group- adenine, guanine, cytosine, uracil What are the four major differences btw DNA and RNA? Answer 1. DNA contains deoxyribose - RNA is ribose 2. DNA: thymine RNA: uracil 3. DNA: double stranded helix RNA: single strand DNA is often described as a coiled ladder. In this description, what two parts of a DNA nucleotide form the uprights? What part forms the rungs? Answer The uprights are the sugar phosphate backbone, and the rungs are the bases. Explain the 2 differences btw hydrolysis and dehydration condensation. Answer During dehydration condensation biomacromolecules are synthesized by joining building block monomers. A water molecule is lost and energy is used. Biomacromolecules are broken down into monomers during hydrolysis when a water molecule is added and energy is released. Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. GLUCOSE Answer Carbohydrate; used as fuel, is referred to as blood sugar in humans and animals Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. Starch Answer Carbohydrate; the form in which plants store glucose Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. Cellulose Answer Carbohydrate; woody tissue in plants and trees, indigestible fiber Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. Triglyceride Answer Lipid; the major form of fuel storage that when broken down produces twice as much energy per gram than carbohydrates Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. Phopholipid Answer Lipid; the major constituent of cell membranes Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. Hemoglobin Answer Protein; carries oxygen in the blood Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. DNA Answer Nucleic Acid; contains genetic material of cells Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. RNA Answer Nucleic Acid; part of the protein-synthesizing operation of the cell Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. Cholesterol Answer Lipid; component of animal cell membranes that, when in excess, can form plaque on artery walls Tell whether each of the following is carbohydrate, lipid, protein, or nucleic acid. Then explain the use of each. ATP
