Ap Bio Unit 2 MCQ study guide correctly answered rated A+ 2023/2024

Ap Bio Unit 2 MCQ study guideWhich of the following functions is the cell type most likely specialized to perform? - correct answer The production and secretion of proteins. Which of the following cellular deficiencies would most likely be related to these MT-ND1 mutations? - correct answer The cell is unable to complete reactions related to electron transport and ATP production. Which cellular component will be found in the widest range of organisms in the sample? - correct answer The ribosome, since all organisms need to synthesize proteins. Which of the following conclusions about the radiolabeled amino acid is best supported by the results of the experiment? - correct answer It was mostly incorporated into proteins that regulate and manage metabolic reactions. Which of the following claims about the effects of the valinomycin treatment is best supported by the data presented in the table? - correct answer The valinomycin treatment caused a decrease in the activity of the mitochondria. Which of the following conclusions about increasing the number of folds in the inner mitochondrial membrane is best supported by the results of the experiment? - correct answer It increases the surface area available for ATP production, which results in faster cell growth. Based on the data which cell is likely to be most effective In the exchange of materials? - correct answer CELL 2. Which of the following provides an accurate calculation of the surface area to volume ratio of an HS red blood cell, as well as a prediction of its affect on the efficient transferring of oxygen compared to a normal red blood cell? - correct answer The ratio is 0.89, and the cells are LESS efficient at transferring oxygen. Which of the following best describes how the ratio of the density of stomata (stomata per mm^2) per CO2 concentration (ppm CO2) changes as the CO2 concentration increases? - correct answer The ratio DECREASES from 0.86 to 0.63, because fewer stomata are needed at higher CO2 concentrations. Which of the following indicates where testosterone enters the cell and why is able to cross at that point? - correct answer 1, because testosterone is nonpolar and can diffuse through the membrane. Based on the figure which of the following statements best describes the relationship between regions 1 and 2 of the protein? - correct answer Region 1 is hydrophilic because it interacts with an aqueous environment, whereas region 2 is hydrophobic because it interacts with the interior of the membrane. Which of the following models shows how cholesterol molecules most likely interact with the phospholipid by layer of a cells plasma membrane? - correct answer D) they r embedded in the phospholipid bilayer What should a team of students do next to obtain data that are more inclusive? - correct answer Repeat the process with other salt concentrations. What additional procedure would best help determine whether these movements are due to active transport or passive transport? - correct answer Use two additional treatments, one containing only ethyl alcohol and one containing only acetate. Include a substance known to block ATP use by the plasma membrane. Compare the graphs of these two treatments to the original graph. Based on their observations, what should the researchers do to further clarify how the availability of the protein outside the cells affects the rate of endocytosis of the protein? - correct answer Incubate the cells in the presence of several different concentrations of the protein. Which of the following best predicts what will happen to the lysosomal enzymes if the proteins that transport H+ ions from the cytosol into the lysosome are damaged? - correct answer The lysosomal enzymes will NOT become active, since there will be no active transport of H+ ions. Which of the following transport mechanisms will be affected most directly by a temporary shortage of ATP molecules inside the cell? - correct answer The transport of GLUCOSE molecules against a concentration gradient.
