Impairment in the function of peroxisomes would result in: A) inadequate sites for protein synthesis. B) an inability to transport cellular products across the cell membrane. C) insufficient energy production within a cell. D) accumulation of free radicals in the cytoplasm. 14. After several months of trying to conceive, a couple is undergoing fertility A Conceptual Approach to The Mechanisms of Disease 3rd Edition Braun Test Bank testing. Semen analysis indicates that the mans sperm have decreased motility, a finding that is thought to underlie the couples inability to become pregnant. A Conceptual Approach to The Mechanisms of Disease 3rd Edition Braun Test Bank Which of the following cellular components may be defective within the mans sperm? A) Ribosomes B) Microtubules C) Mitochondria D) Microfilaments 15. Which of the following statements is true of glycolysis? A) Glycolysis requires oxygen. B) Glycolysis occurs in cells without mitochondria. C) Glycolysis provides the majority of the bodys energy needs. D) Glycolysis produces energy, water, and carbon dioxide. 16. Which of the following membrane transport mechanisms requires the greatest amount of energy? A) Facilitated diffusion B) Passive transport C) Vesicular transport D) Simple diffusion 17. A male patient with a diagnosis of type 1 diabetes mellitus is experiencing hyperglycemia because he lacks sufficient insulin to increase the availability of glucose transporters in his cell membranes. Consequently, his cells lack intracellular glucose and it accumulates in his blood. Which of the following processes would best allow glucose to cross his cell membranes? A) Facilitated diffusion B) Simple diffusion C) Secondary active transport D) Endocytosis 18. Which of the following statements is true of skeletal muscle cells? A Conceptual Approach to The Mechanisms of Disease 3rd Edition Braun Test Bank A) Skeletal muscle cells each have an apical, lateral, and basal surface. A Conceptual Approach to The Mechanisms of Disease 3rd Edition Braun Test Bank B) They are closely apposed and are joined by cell-to-cell adhesion molecules. C) Their basal surface is attached to a basement membrane. D) Skeletal muscle is multinucleated, lacking true cell boundaries. 19. Which of the following body tissues exhibits the highest rate of turnover and renewal? A) The squamous epithelial cells of the skin B) The connective tissue supporting blood vessels C) The skeletal muscle that facilitates movement D) The nervous tissue that constitutes the central nervous system 20. A patient with a pathophysiologic condition that affects the desmosomes is most likely to exhibit: A) impaired contraction of skeletal and smooth muscle.
