[Campbell Biology P.76] Which of the following statements accurately describes the findings... | Practice Question
Which of the following statements accurately describes the findings of Dr. Olden's highly cited research on fibronectin?
A: Fibronectin was found to be present on the surface of cancer cells but not normal cells.
B: Carbohydrates were essential for fibronectin to be exported from the cell.
C: Tunicamycin was used to prevent protein synthesis, leading to fibronectin's structural instability.
D: Carbohydrates were crucial for stabilizing the structure of fibronectin, though not for its export.
Explanation
The text states: 'We showed that carbohydrates weren't necessary for export, but instead they were important for stabilizing the protein's structure.' This directly confirms option D.
