Terms in this set (16)Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic processes. To function properly, the organelles must move substances across their membrane. Which of the following statements describes a feature shared by mitochondria and the endoplasmic reticulum that
increases the efficiency of their basic functions? The answer is B. Compared with a smooth membrane, a highly folded membrane has a greater surface area that increases the rate of material transport across the membrane and provides more support for membrane-associated processes. All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum. Which of the following best describes a process that occurs within the Golgi complex? A. Enzymatic modification of newly synthesized integral membrane proteins The correct answer is A. The Golgi complex is a membrane-bound structure to which some proteins are moved from the rough endoplasmic reticulum, where they are enzymatically modified before being sent to a cellular membrane. Cells contain smaller components called organelles that are necessary for a cell's survival. Organelle functions have often been compared to components of larger systems. Which of the following difference between the rough and smooth endoplasmic reticulum (ER) is explained by the structural differences between them? The correct answer is D. The ribosomes associated with rough ER synthesize proteins that are then exported from the cell. What most likely causes the trends in oxygen concentration shown in the graph above? The correct answer is D. A student placed 20 tobacco seeds of the same species on moist paper towels in each of two petri dishes. Dish A was wrapped completely in an opaque cover to exclude all light. Dish B was not wrapped. The dishes were placed equidistant from a light source set to a cycle of 14 hours of light and 10 hours of dark. All other conditions were the same for both dishes. The dishes were examined after 7 days, and the opaque cover was permanently removed from dish A. Both dishes were returned to the light and examined again at 14 days. According tot he results of this experiment, germination of tobacco seeds during the first week is The correct answer is A. A researcher claims that some bacteria contain factors that influence the function of a particular enzyme but other bacteria do not. To test the claim experimentally, the researcher will grow two different bacterial strains in separate liquid cultures and isolate the contents of the cells in each culture. The researcher will add different combinations of cellular contents, substrate, and enzyme to test tubes containing a buffer solution adjusted to the optimal pH of the enzyme and then measure the rate of production formation. The design of the researcher's experiment is presented in Table 1. Which of the following statements best justifies the inclusion of test tubes 3 and 7 in the experiment? The correct answer is A. The researcher will add cellular contents and the substrate but not the enzyme to test tubes 3 and 7. As such, test tubes 3 and 7 will show whether the cellular contents have enzymatic activity. Which
of the following is most directly responsible for water''s unique properties? The correct answer is D. Which of the following is responsible for the cohesive property of water? The correct answer is C. A feature
of organic compounds NOT found in inorganic compounds in the presence of The correct answer is C. Which of the following statements best describes how organisms such as rabbits obtain the carbon necessary for building biological molecules? The correct answer is B. Which of the following is an accurate description of the process shown in figure 1? The correct answer is D. This reaction combines two smaller amino acids to form a dipeptide (a step in the formation of a protein) with the release of water. The presence of nitrogen is consistent with the both amino acids and proteins. The combining of smaller molecule with the release of water is a dehydration synthesis reaction. Which of the following best describes the formation of the bond shown in Figure 1? The correct answer is C. Even though the water molecule that is produced is not shown in Figure 1, it shows the formation of the peptide bond and the missing H and OH. Which statement is the most accurate description of the reaction shown in Figure 1? The correct answer is D. The reaction shows the polypeptide being split into two smaller units with the addition of a hydroxide ion and a hydrogen ion from water. This facilitates the breaking of the bond holding the polypeptide together. The synthesis of protein or carbohydrate polymers always produces which of the following as a byproduct. The correct answer is E. Water and Ammonia interact to form hydrogen bonds, as represent in the figure. Which statement best helps explain the formation of the hydrogen
bond represented in the figure? The correct answer is B. The greater electronegativity of oxygen and nitrogen compared to hydrogen makes for unequal sharing of electrons, which associated with the oxygen and nitrogen atoms and partial positive charges associated with the hydrogen atoms in both molecules. The attraction between opposite charges results in formation of the hydrogen bond represented in the figure. Figure 1 is a diagram of
water molecule at the air-water interface at the surface of a pond. Based on figure 1, which of the following best describes how the properties of water at an air-water interface enable an insect to walk on the water's surface. The correct answer is D. Hydrogen bonds form between water molecules due to the partial charges produced as a result of the
polarity of the water molecule.
