I didn't involve the questions that aren't directly from AP Classroom. Terms in this set (35)Which of the following is responsible for the cohesion of water? hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule T or F: 95% confidence intervals are used in AP Bio to show that you are 95% confident in your data false Amylase is an enzyme that converts carbohydrate polymers into monomers. Glycogen synthase is one of the enzymes involved in converting carbohydrate monomers into polymers. Which of the following best explains the reactions of these enzymes? amylase aids in the removal of water molecule to form covalent bonds whereas glycogen synthase aids in the addition of water molecule to break covalent bonds What is the percentage of thymine in nucleotide of RNA? 0% (thymine isn't present in rna, its uracil) How many bonds can carbon make? 4 What type of macromolecules make up enzymes? protein macromolecules Endergonic reactions release energy false Which of the following best explains the reaction specificity of an enzyme? the shape and charge of the substrate are compatible with the active site of the enzyme All cells have mitochondria false Which of the following statements about mitochondrial chemiosmosis is NOT true? the potential energy released from the mitochondrial proton gradient is used to produce atp During respiration, most ATP is formed as a direct result of the net movement of protons down a concentration gradient Which of the following statements best helps justify the inclusion of group 2 as one of the controls in the experiment? It will show whether the changes observed in group 1 depend on the metabolic activity of soil bacteria. Which of the following statements correctly explains the observed effect of the acetylcholine concentration on the rate of the enzyme-catalyzed reaction? the active site of AChE is specific for acetylcholine, and only one substrate molecule can occupy the active site at a time A set of five additional test tubes were prepared and used as controls. Which of the following best describes the contents expected to be contained in one of the five control test tubes? pH 4 buffer solution and hydrogen peroxide only Which of the following best predicts the effect of disrupting the proton gradient in BAT? the pH of the matrix will increase, allowing the production of more ATP per gram of substrate All organisms do photosynthesis false During aerobic cellular respiration, oxygen gas is consumed at the same rate as carbon dioxide gas is produced. In order to provide accurate volumetric measurements of oxygen gas consumption, the experimental setup should include which of the following? a substance that removes carbon dioxide gas The diagram above represents a typical rod-shaped bacterium. Which of the following best describes a feature shown in the diagram that is unique to archaea and bacteria? the organism does not have a nuclear membrane surrounding its genetic material Which of the following best describes how the ratio of the density of stomata per CO2 concentration changes as the CO2 concentration decreases? the ratio decreases from 0.86 to 0.63, because fewer stomata are needed at higher CO2 concentrations What evolutionary advantage does compartmentalization of core metabolic processes offer eukaryotes? evolution of a nucleus in eukaryotes separates the processes of transcription and translation and they can be regulated separately Which of the following descriptions of cell type I and cell type II are most consistent with the data? cell type 1: animal cell surrounded by a plasma membrane only An investigator wants to understand whether a newly found membrane is involved in membrane transport of a certain particle. which investigation will help determine whether the new membrane protein is a channel protein involved in membrane transport? add more of the proteins to the plasma membrane and measure the rate of the particle movement All of the following changes would be likely to decrease the rate of transpiration at 8 A.M except increasing the water potential of the soil The team wants to extend the research project. What should the team of students do next to obtain data that are more conclusive? 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? 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 the model presented in figure 1, which of the following changes will most likely result from a depletion of available ATP stores inside the cell? the na+ concentration inside the cell will increase Which of the graphs below best represents the predicted change in mass over time of the dialysis bag in the beaker to which albumin was added? b (graph with straight line then decrease in mass) Most cells that have become transformed into cancer cells have which of the following when compared to normal, healthy cells? shorter cell cycle Which of the following best describes the role of water in photosynthesis? water molecules combine with stored carbon molecules to produce glucose The hydrolytic enzymes are most likely to accumulate in which of the following cellular structures? golgi complex The amino acid in Figure 1 is found in a region of a polypeptide that folds away from water. Which part of the amino acid most likely contributes to the hydrophobic behavior of the region of the polypeptide? ... Consider this data chart. What would be the most appropriate representation of results documented in the table B (bar graph, standard error of the mean, dashed line) Which of the following best describes the structures of carbohydrates? they occur as monomers, chains of monomers, and branched structures Which of the following best describes the hydrolysis of carbohydrates? the removal of a water molecule forms a covalent bond between sugar monomers When a substance moves across the plasma membrane along a concentration gradient at a rate faster than would be expected by simple diffusion alone but without the expenditure of metabolic energy. The process is best described as facilitated diffusion Sets with similar termsSemester 1 Midterm AP Biology50 terms Alayssa_Camano Cell and Homeostasis Unit Exam30 terms haleygillilan AP Bio Fall Final 2018- add genetics test85 terms tnunn32 Biology- Photosynthesis46 terms NasirTheGreat1 Other sets by this creatorNevada DMV Written Test 202133 terms asapjanelle Biology Unit 5 Socrative7 terms asapjanelle AP Biology Unit 4 Questions28 terms asapjanelle AP Bio Final Exam 1, AP Biology Socrative Questions87 terms asapjanelle Other Quizlet setsSocial Problems Final173 terms

He did this because he believed there may have been a fox trying to get at the chickens. 4 answers QUESTION What is Albumin 25% used for? 15 answers Why is it essential for a eukaryotic cell to compartmentalize its functions quizlet?Explain the advantages of compartmentalization in eukaryotic cells. Because the cell's compartments provide different local environments that facilitate specific metabolic functions, incompatible processes can go on simultaneously inside the same cell.
Which of the following best explains the advantage These projections provide the cell quizlet?Which of the following best explains the advantages of these projections provide the cell? The projections increase the surface area-to-volume ratio of the cell which allows for more efficient nutrient exchange with the environment.
Which of the following best explains the advantage these projections provide for the cells?Which of the following best explains the advantage these projections provide the cell? The projections increase the selectivity of the membrane because the small size of the projections limits the number of transport proteins that can be embedded in the membrane.
