2. Question 2
   A skeletal muscle biopsy from a patient with chronic fatigue shows many enlarged organelles with abundant inner membrane folds (cristae). Which cellular function is most directly supported by an increased number of these organelles?

3. Question 3
   A nurse is reviewing a peripheral blood smear report noting that mature red blood cells lack a nucleus and most organelles. Which organelle is absent, explaining why these cells cannot synthesize new proteins after maturation?

   RibosomesPeroxisomesLysosomesCentrioles

4. Question 4
   A nurse is learning why airway epithelial cells can move mucus upward to help clear inhaled pathogens. Which cellular structure is primarily responsible for the coordinated beating that propels mucus along the respiratory tract?

5. Question 5
   A nurse is reviewing an electron microscopy image from a patient’s liver biopsy. The report notes an increased number of small, membrane-bound organelles containing oxidative enzymes that help break down very-long-chain fatty acids and detoxify reactive oxygen species. Which organelle is being described?

   Rough endoplasmic reticulumLysosomePeroxisomeNucleolus
