Attachment Assembly Release Synthesis Entry Chapter 13, Viral Replication Question 10 (TCO 7) The infectious particles of fungi have RNA genomes and lack a capsid. They are therefore similar to _____. bacteriophages enveloped viruses prions viroids lysogens Chapter 13, Other Parasitic Particles Question 11 (TCO 5) Explain why fermentation is a necessary alternative to respiration in many cells. VERSION 2 Question 1.1. (TCO 5) Anabolic reactions may be characterized as _____. (Points : 2) exergonic breaking large molecules into smaller molecules forming large molecules from smaller molecules producing ATP None of the above Question 2.2. (TCO 5) Enzymes known as lyases participate in _____ reactions. (Points : 2) anabolic catabolic both anabolic and catabolic neither anabolic nor catabolic oxidation-reduction Question 3.3. (TCO 5) Which of the following statements about fermentation is incorrect? (Points : 2) Aerobic bacteria will undergo fermentation instead of cellular respiration when oxygen is present. Fermentation results in the production of fewer ATP molecules than cellular respiration. End products of fermentation include ethanol, and acetic acid. The presence of fermentation end products is useful in identifying unknown bacteria in the laboratory. Fermentation is involved in the production of a number of foods, including yogurt, sauerkraut, and cheese. Question 4.4. (TCO 5) The metabolic processes called fermentation _____. (Points : 2) produce substrates for the Krebs cycle are alternatives for the pentose phosphate pathway occur only when oxygen is not readily available occur only when oxygen is readily available produce substrates for glycolysis Question 5.5. (TCO 6) An aligned pair of homologous chromosomes is called a _____. (Points : 2) chromatid spindle tetrad coenocyte gamete Question 6.6. (TCO 6) Study of fungus is called _____. (Points : 2) fungology mycology pathology toxicology mushroomoology Question 7.7. (TCO 6) Lichens are composed of a symbiosis of fungi and which of the following? (Points : 2) Green algae Cyanobacteria Euglenoids Cyanobacteria or green algae Euglenoids or dinoflagellates Question 8.8. (TCO 7) During the intracellular state, a virus exists as _____. (Points : 2) a lipid a protein a nucleic acid both a protein and a nucleic acid both a lipid and a nucleic acid Question 9.9. (TCO 7) Put the following stages of a lytic replication cycle in order from earliest to latest. I. Synthesis II. Assembly III. Attachment IV. Release V. Entry (Points : 2) III, V, I, II, IV III, II, V, I, IV V, III, II, IV, I I, III, V, II, IV I, II, III, V, IV Question 10.10. (TCO 7) How are prions different from all other known infectious agents? (Points : 2) They cannot reproduce outside a cell. They act as slow viruses. They cause neurological problems. They can be destroyed by incineration. They lack nucleic acid. 1. (TCO 5) Describe the mechanism of feedback inhibition and the role this process plays in controlling enzyme activity. (Points : 10)
