Which statement best describes the cellular function of metabolic absorption? A. Cells can produce proteins. B. Cells can secrete digestive enzymes. C. Cells can take in and use nutrients. D. Cells can synthesize fats. Correct Answer: C Rationale: In metabolic absorption, all cells take in and use nutrients and other substances from their surroundings. This is a fundamental cellular function that enables cells to acquire the raw materials needed for growth, repair, and energy production. Options A, B, and D describe other specialized cellular functions (protein synthesis, secretion, and lipid synthesis) but do not define metabolic absorption. DIF: Easy KEY: Comprehension MSC: General NOT: Requires understanding of basic cellular functions. ________________________________________ 2. Where is most of a cell's genetic information, including RNA and DNA, contained? A. Mitochondria B. Ribosome C. Nucleolus D. Lysosome Correct Answer: C Rationale: The nucleus contains the nucleolus, a small dense structure composed largely of RNA, most of the cellular DNA, and DNA-binding proteins (histones) that regulate its activity. The mitochondria are responsible for cellular respiration and energy production. Ribosomes' chief function is to provide sites for cellular protein synthesis. Lysosomes function as the intracellular digestive system . DIF: Easy KEY: Knowledge MSC: General NOT: Distinguishes among organelles based on function. ________________________________________ 3. Which component of the cell produces hydrogen peroxide (H₂O₂) by using oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction? A. Lysosomes B. Peroxisomes C. Ribosomes D. Endosomes Correct Answer: B Rationale: Peroxisomes are so named because they usually contain enzymes that use oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction that produces H₂O₂, which is a powerful oxidant and potentially destructive if it accumulates or escapes from peroxisomes. Ribosomes are RNA-protein complexes. Lysosomes are saclike structures containing digestive enzymes. Endosomes are vesicles pinched off from the cellular membrane. DIF: Moderate KEY: Comprehension MSC: General NOT: Requires knowledge of peroxisomal function.
