- Q1Which molecule synthesized by plants is a major source of energy for cellular processes in both plants and animals?Nucleic acidChlorophyllWaxGlucose30sB.4.B: Cellular Processes
- Q2The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environment. What conditions cause the contractile vacuole to fill with water?The temperature of water in the vacuole is lower than the temperature of its environmentThe concentration of water inside the cell is the same as the concentration outside the cellThe concentration of water is greater outside the cell than inside the cellThe temperature of water in the vacuole is higher than the temperature of its environment30sB.4.B: Cellular Processes
- Q3In the early 1900s a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fact that DNA could not be found outside the nucleus led scientists to believe that another substance was also involved in the synthesis of protein in the cytoplasm. In the 1940s scientists performed an experiment that ultimately identified the site of protein synthesis. They also identified the molecule responsible for transporting information from the nucleus to the site of protein synthesis. What was this newly identified molecule?A genemRNAATPThymine30sB.4.B: Cellular Processes
- Q4This diagram shows cellular activity across a cell membrane. Which two processes does this diagram most directly model?Homeostasis and transport of moleculesTransport of molecules and energy conversionsEnergy conversions and synthesis of new moleculesSynthesis of new molecules and homeostasis30sB.4.B: Cellular Processes
- Q5Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the metabolism of one molecule of glucose. Which cellular process results in this amount of ATP production?Aerobic cellular respirationPhotosynthesisAnaerobic cellular respirationProtein synthesis30sB.4.B: Cellular Processes
- Q6Some students used vinegar to dissolve away the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions. Which statement best describes the role of the cell membrane in this model?The cell membrane removes solutes from the environmentThe cell membrane allows water to enter and leave the cellThe cell membrane is an impermeable barrier that prevents water from entering the cellThe cell membrane allows solutes to enter the cell, which causes the cell to shrink30sB.4.B: Cellular Processes
- Q7Which group of organelles is directly responsible for the production of new molecules within a cell?The endoplasmic reticulum, plastids, and vacuolesGolgi apparatuses, lysosomes, and the plasma membraneThe nucleolus, vacuoles, and ribosomesRibosomes, the endoplasmic reticulum, and Golgi apparatuses30sB.4.B: Cellular Processes
- Q8The cellular process known as the sodium-potassium pump was discovered in the 1950s by Jens Christian Skou, a Danish scientist. This process is a form of active transport that moves three sodium ions to the outside of a cell for every two potassium ions that it moves into the cell. Which of these best explains why energy is needed for active transport?Ions are negatively chargedIons are trapped inside the plasma membraneIons are attached to large proteinsIons are moved against the concentration gradient30sB.4.B: Cellular Processes
- Q9Which of these statements best explains the process of energy conversion that takes place in the mitochondria?Oxygen molecules release energy in the form of heat during combustion reactionsEnergy is required for carbon dioxide molecules to form six-carbon sugar moleculesWater molecules and radiant energy are necessary for anaerobic respiration to take placeThe energy in the bonds of glucose molecules is transferred to the phosphate bonds in ATP30sB.4.B: Cellular Processes
- Q10Which cellular process takes place in the ribosomes that are bound to the endoplasmic reticulum?The synthesis of new proteinsThe conversion of radiant energy to glucoseThe replication of nucleic acidsThe breakdown of waste material30sB.4.B: Cellular Processes
- Q11The diagram illustrates the activity of vesicles during a cellular process. Which statement best explains the function of the vesicles?Transporting packaged molecules from the Golgi apparatus to be released out of the cellExtracting portions of the Golgi apparatus to be regenerated for growth within the cellExchanging genetic information between the Golgi apparatuses of separate cellsDelivering packaged materials to the Golgi apparatus for protein synthesis60sB.4.B: Cellular Processes
- Q12When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by -decreasing the rate of glucose movement into the cellincreasing the rate of cellular divisionincreasing the rate of cellular respiration in mitochondriadecreasing the rate at which carbon dioxide is removed from the cell60sB.4.B: Cellular Processes
